LUCERNE, Calif. — A meeting for Lucerne community members to discuss issues of concern will be held this week.
The Lucerne community meeting will take place at 6 p.m. Thursday, Jan. 19, in the multipurpose room at Lucerne Elementary School, 3351 Country Club Drive.
The meeting ID is 857 2312 7967, the passcode is 13931.
Kurt McKelvey, who has served as chair of the Lucerne Area Town Hall, will moderate the meeting.
On the agenda is a discussion of the Scotts Valley Band of Pomo Indians’ proposal to use the Lucerne Hotel to house dozens of out-of-county homeless youth and young adults.
The Lucerne Area Town Hall passed a resolution at its December meeting condemning the proposal.
Also on the agenda, there will be discussion for the need for self-determination for the community of Lucerne.
There also will be a discussion of neglected county maintenance issues in Lucerne.
Gov. Gavin Newsom on Saturday night announced that the White House has approved California’s request for a Presidential Major Disaster Declaration to support the state’s emergency response to ongoing storm impacts including flooding, mudslides and landslides in communities across the state.
“California is grateful for President Biden’s swift approval of this critical support to communities reeling from these ongoing storms,” said Governor Newsom, who earlier on Saturday met with evacuated residents in Merced County and surveyed damage in the area. “We’ll continue to work in lockstep with local, state and federal partners to help keep Californians safe and make sure our communities have the resources and assistance they need to rebuild and recover.”
The Presidential Major Disaster Declaration will help Californians in impacted counties through eligibility for several programs and supports, and includes public assistance to help state, tribal and local governments with ongoing emergency response and recovery costs and hazard mitigation.
Saturday’s declaration makes federal funding available to affected individuals in the counties of Merced, Sacramento and Santa Cruz. Additional impacted counties may be included once storm conditions allow state, local and federal officials to safely assess the scope of damage.
Earlier this week, President Biden approved the governor’s request for a Presidential Emergency Declaration to bolster state, local and tribal government storm response efforts.
Gov. Newsom has activated the State Operations Center to its highest level and proclaimed a state of emergency statewide.
Amid ongoing storms and flooding, the state and its partners are working quickly to initiate recovery efforts and help Californians return home as soon as it is safe to do so.
Work is underway to remove hazardous waste and clear debris and there are teams on the ground conducting damage assessments documenting the extent of the losses so that the state can maximize its requests for federal aid.
Residents and business owners who sustained losses in the designated areas can begin applying for assistance by registering online at www.DisasterAssistance.gov or by calling 1-800-621-3362 or 1-800-462-7585 TTY
The Research Brief is a short take about interesting academic work.
The big idea
To reduce the harmful health effects of sitting, take a five-minute light walk every half-hour. That’s the key finding of a new study that my colleagues and I published in the journal Medicine & Science in Sports & Exercise.
We asked 11 healthy middle-aged and older adults to sit in our lab for eight hours – representing a standard workday – over the course of five separate days. On one of those days, participants sat for the entire eight hours with only short breaks to use the bathroom. On the other days, we tested a number of different strategies to break up a person’s sitting with light walking. For example, on one day, participants walked for one minute every half-hour. On another day, they walked for five minutes every hour.
Our goal was to find the least amount of walking one could do to offset the harmful health effects of sitting. In particular, we measured changes in blood sugar levels and blood pressure, two important risk factors for heart disease.
We found that a five-minute light walk every half-hour was the only strategy that reduced blood sugar levels substantially compared with sitting all day. In particular, five-minute walks every half-hour reduced the blood sugar spike after eating by almost 60%.
That strategy also reduced blood pressure by four to five points compared with sitting all day. But shorter and less frequent walks improved blood pressure too. Even just a one-minute light walk every hour reduced blood pressure by five points.
In addition to physical health benefits, there were also mental health benefits to the walking breaks. During the study, we asked participants to rate their mental state by using a questionnaire. We found that compared with sitting all day, a five-minute light walk every half-hour reduced feelings of fatigue, put participants in a better mood and helped them feel more energized. We also found that even walks just once every hour were enough to boost mood and reduce feelings of fatigue.
Along with short, frequent walks, a long daily walk could add years to your life.
Because of technological advances, the amount of time adults in industrialized countries like the U.S. spend sitting has been steadily increasing for decades. Many adults now spend the majority of their day sitting. This problem has only gotten worse since the start of the COVID-19 pandemic. With the migration to more remote work, people are less inclined to venture out of the house these days. So it’s clear that strategies are needed to combat a growing 21st century public health problem.
Current guidelines recommend that adults should “sit less, move more.” But these recommendations don’t provide any specific advice or strategies for how often and how long to move.
Our work provides a simple and affordable strategy: Take a five-minute light walk every half-hour. If you have a job or lifestyle where you have to sit for prolonged periods, this one behavior change could reduce your health risks from sitting.
Our study also offers clear guidance to employers on how to promote a healthier workplace. While it may seem counterintuitive, taking regular walking breaks can actually help workers be more productive than working without stopping.
What still isn’t known
Our study primarily focused on taking regular walking breaks at a light intensity. Some of the walking strategies – for example, one-minute light walks every hour – did not lower blood sugar levels. We don’t know if more rigorous walking would have provided health benefits at these doses.
What’s next
We are currently testing over 25 different strategies for offsetting the health harms of prolonged sitting. Many adults have jobs, such as driving trucks or taxis, where they simply cannot walk every half-hour. Finding alternative strategies that yield comparable results can provide the public with several different options and ultimately allow people to pick the strategy that works best for them and their lifestyle.

We sure have been getting a lot of rain, we need it. My question is: How much rain will it take to fill Clear Lake to full, like a normal year? How do I find out where to see the lake levels and when do we have to worry if it will flood?
Thanks!
From Raining on Randy on Rocky Point
Dear Raining on Randy,
Thanks for this excellent question! I have received this question from several folks, so I thought it best to tackle it in today’s column.
First I will provide some important links and resources for learning about lake levels and stream heights and flows. Then I will provide you with some calculated outlooks for where the lake is going with the rain we received and what we can expect to see with any more rain. I will also provide you the estimated amount of rain needed to get a “full” lake, and the amount of rain that would lead to several different flood level lake stages.
Measuring Lake Levels
Clear Lake level is determined in a very unique way, using the Rumsey gauge to measure lake levels. I described this in my column, “Learning about Lake Levels” from Oct. 17, 2021.
Daily lake level data is measured from an in-lake gauge (#11450000) operated and maintained by the United States Geological Survey (USGS). The gauge has historically been located on a pier at Lake County Vector Control District in Lakeport, but sometimes during droughts, when there is a lack of water depth at the gauge’s normal location, the gauge will be temporarily moved to the 5th street ramp at Library Park in Lakeport. USGS maintains that all online data is provisional until verified and confirmed and usually that can take several months.
Figure. Lake Level data for the period of December 14, 2022 - January 14, 2023 (Orange) compared to historic median (dotted line on top) for the last previous 109 years (1913-2022) and to the Lake level during the same period last year (purple). Source: USGS.
The lake, when full, will be 7.56 on the Rumsey gauge. As I write this article, the lake is currently at 2.84 Rumsey, so about 40% full. But remember, that we were below zero Rumsey in December, at about -2.25 Rumsey, until we started getting these rain events, so we had to get to zero first, before rain could start to fill the Lake to full.
However, if you notice the historic median lake level on the graph (dotted, top line), you will notice that we have met the historic median, making the lake level today very similar to the previous 109 years, with 50% of the years being more than that value and 50% being less (definition of median).
If you want to know stage height data from other gauges around the state, I suggest you explore the Sierra Nevada River Forcast Network Interactive Map. On this site, you can find different lakes or rivers with real-time gauges measuring lake levels, stream height and stream flow.
This also has a great interactive map, where you can see what gauges are where and what type of information they are collecting such as precipitation, stage height, flow, and some gauges also provide forecast conditions.
Also, the Lake County Water Resources Department monitors the daily lake level and can provide that to you by phone at 707-263-2344, if you do not have access to the website.
Streaming real-time stream data
There are lots of resources available online for anyone to access real-time stream and river data. Please refer to my previous column, “Lady of the Lake: Streaming stream and river data in real-time” from October 31, 2021.
In that column, I reviewed two of my favorite websites for accessing stream data, including The California Nevada River Forecast Center, the CNRFC, and California Data Exchange Network, or CDEC.
The CNRFC, is a field office of the National Weather Service located in Sacramento, California. The CNRFC is co-located with the Sacramento NWS Forecast Office, CDWR, and United States Bureau of Reclamation. The NWS is an agency of the National Oceanic Atmospheric and Administration, or NOAA, under the United States Department of Commerce.
The CNRFC is great for monitoring flash flooding, river forecasting, managing water resources, or learning about hydrometeorology. Also the maps and graphs are very easy to use and interpret. This site can also provide temperature conditions and predictions which can be used for frost protection planning, for example. Additionally, this site has incorporated some post-fire debris flow warning layers. So if you live in an area that has a burn scar nearby, this website can help you to visualize those areas most at risk to post-fire flooding and debris flows.
The next resource is California Data Exchange Center, or CDEC. This website is managed by the California Department of Water Resources and while it does have some prediction power, the majority of gauge information here is real-time and archival. However, it’s pretty easy to use and has a large network of gauges and data that expands across all of California.
One thing about the CDEC is the data is focused on river information. The tabs at the top of the home page provide a lot of the type of data and tools available, and makes it easy to search for what you might need. Historic water data is also easily available on CDEC, making it easy to conduct a study on your local stream or river.
One thing to be aware of with CDEC is that the website can get pretty busy and bogged down during popular use times. If there is a heavy storm event and people and agencies are looking for river data and flood conditions, this website might get really slow and pages might not load as quickly, so be patient.
In my previous column on stream data, I provided a video tutorial on how to access CNRFC data from your own computer. This video is very useful for someone who has no prior experience getting stream data from online resources.
Stream and Lake gauges in our area
Here I provide some of the quick links for the local gauges for streams and lakes of interest.
Below is a list of some *NEW* stream gauges installed this year thanks to the Blue Ribbon Committee for the Rehabilitation of Clear Lake Funds with partnerships from USGS, UC Davis, County of Lake Water Resources, Habematolel Pomo of Upper Lake, and City of Clearlake. These gagues are temporary but when fully operational will report stage height, flow, water temperature, and turbidity (how cloudy the water is).
Now, to answer your last question Randy; how much rain does it take to raise Clear Lake levels and how much is too much rain, or will result in flooding conditions.
It’s kinda remarkable that a month ago we were worried about another year of severe drought and now we are talking about flooding, but that is the new climate paradigm we are living in.
If you read my previous column about streaming stream data, you will notice that I refer to myself as a “data snob” because I like data clean, organized, and I like to use data to answer interesting questions. Randy, your question is very interesting to me, and I researched what was out there when it came to how much rain corresponds to a rise in lake level.
I got several answers, in conversations with folks who have lived here on the lake a long time. The most common answer was that every 4-5 inches of rain, we see about a foot of lake level increase. So, if we got 10 inches of rain, we would expect to see about 2 feet of lake level increase.
Logistically, the lake is rising from the rain itself (collecting in the lake) and the collection of runoff from the landscape and tributaries flowing into the lake contributes to the lake level increase.
Me, being a data snob, needed to see the numbers. Unfortunately for me, I am not an engineer and don’t have an engineering brain, but I dusted off my old mental file of math and algebra and attempted to understand the relationship between the rain and lake level rise. Full acknowledgement to Mr. Blackwell, my high school Algebra teacher - you were right, sometimes we do use this stuff in real life, Mr. B!
First I downloaded daily rain data from CDEC for Lake County, CA. The closest station with daily accumulated rain was the Whispering Pines (WSP, CA Dept of Water Resources/DFM-Hydro-SMN). For these purposes I used accumulated rain, and I converted the data to start from zero in December, as opposed to 10 inches accumulated for the entire water year which runs from October to September. I chose December because that is when we first started getting rain for this series of rain “events” and started seeing significant lake level rise.
I didn’t want to include accumulated rain from earlier in the year, for example from mild showers in October, to interfere with my calculations today, as that rain is probably, most likely, not contributing to lake levels we are seeing now.
Then I downloaded daily lake level data, from the Lakeport gauge station housed at Vector Control, as described above in the beginning of this column. Then I plotted both of these data on a scatter plot, with rain on the X axis (independent variable) and lake level rise on the Y axis (dependent variable). Then I calculated the slope of the data and fit a line to the slope.
Heads up, algebra alert, to calculate the slope of a line, or the “rise over run” of a line, we have to use the formula m=(y2-y1)/(x2-x1), with m= slope, x1 and x2 being two numbers in a list of x (rain) and ya and y2 being two numbers in the list of y (lake level). This is also described as the change in the y values over the change in the x values. The slope will answer the question; how much change in lake level will we see when we have one inch of rain?
A key piece to remember is that up until Zero Rumsey water is only going into the system, there is no outflow from the lake until the lake level gets to Zero Rumsey and only after that can water start to flow over the Grigsby Riffle in Cache Creek.
So this added another variable into my calculations and plot, even though we are still getting quite a bit of rain, we also are seeing water leave the system. So, here we go algebra again, I calculated a separate slope for when the lake is over zero Rumsey, to account for the precipitation, inflow from tributaries, and outflow into and down Cache Creek.
To my surprise (but not really) the slopes are pretty different. The slope for the rain-lake level relationship before zero Rumsey is 0.14 and the slope for after the lake is above zero Rumsey is 0.26. This means that for every one inch of rain, the lake rises about 0.14 feet or 0.26 feet, depending on if there is outflow or not. So it does take roughly 4 inches of rain to raise the lake one foot - when the lake is at or above zero Rumsey.
It takes quite a bit more rain (about 7 inches) to raise the lake one foot when the lake is negative Rumsey. Mathematically this might not make sense and you might be asking yourself “if water is leaving the system down Cache Creek, how can it take less rain to raise the lake?” And I would answer by asking you to consider the system as a part of the watershed in a post-drought year (of which my data is based).
It takes a lot of rain to infiltrate and soak into the soils, and then it takes a lot more to accumulate into runoff that flows into the lake. Another thing to consider is that the outflow to Cache Creek is very limited, at about 2,500 cubic feet per second (CFS), compared to a single inflowing tributary such as Middle Creek, which can easily reach 3,000 - 5,000 CFS in any given large storm event.
Lasty, Randy, you asked when we should see a “full lake”. The lake is considered full when it reaches 7.56 on the Rumsey gauge, and I estimated that if it receives 45 inches of rain (based on the slope for positive Rumsey) we should be at full lake status. This is about 55 annual accumulation from October.
We have quite a bit to go as we have received about 25 inches in the last three weeks and we are only 40% full. You also asked about flood stage, and I have been receiving lots of inquiries about that too.
How much rain does it take to raise Clear Lake? It depends on if the lake is below or above zero Rumsey. Red data points and slope equation is based on rain and lake level data from Dec 23, 2022 to January 8, 2023. Black data points and slope equation derived from rain and lake level data from Jan. 9 to 13, 2023. Rain data sourced from DWR CDEC WSP Station and Clear Lake level data from USGS Lakeport station 11450000.
According to USGS, and based on 109 years of historic lake levels, when the lake gets to 9 ft Rumsey, it's considered minor flood stage, 11.4 ft is moderate flood stage and major flood stage is when the lake is at or exceeds 12 ft Rumsey. According to the Lake County Water Resources Department Historical Levels of Clear Lake High and Low, there is 10% chance of getting to minor flood stage, and 1% chance of the lake getting to major flood stage in any given year.
Using my rudimentary slope calculations, I have calculated how much rain (continuous, mind you) we would need to get to those stages. This is estimated and only applies with the continuation of the rain series we are seeing. If we see a dry month, the trend might be slightly off, but these are generally good guidelines as the ground is currently saturated and the lake is likely to stay above zero Rumsey.
It would take about 40 inches during this rain event to get to the minor flood stage of 9.0 feet Rumsey (50 annual accumulation from October) and about 52 inches (63 annual) to get to the major flood stage of 12.0 feet Rumsey. Notice that my calculated numbers are not based on annual accumulation (starting in October), but total for the rain events starting in December, as the annual year reset on January 1st.
That is quite a bit to go, but anything can happen in a third year of La Niña, as we have learned.
Sincerely,
Lady of the Lake

Members of the public can help astronomers observe and study the night sky through NASA’s Universe of Learning Exoplanet Watch program. Credit: NASA/Bill Dunford. The Exoplanet Watch project invites you to use your smartphone or personal telescope to help track worlds outside our solar system.
More than 5,000 planets have been confirmed to exist outside our solar system, featuring a wide array of characteristics like clouds made of glass and twin suns. Scientists estimate there could be millions more exoplanets in our home galaxy alone, which means professional astronomers could use your help tracking and studying them.
This is where Exoplanet Watch comes in. Participants in the program can use their own telescopes to detect planets outside our solar system, or they can look for exoplanets in data from other telescopes using a computer or smartphone.
Exoplanet Watch began in 2018 under NASA’s Universe of Learning, one of the agency’s Science Activation programs that enables anyone to experience how science is done and discover the universe for themselves.
Until recently there were limits on how many people could help look through the data collected by other telescopes, but now this program is easily available to anyone. By following the site’s instructions, participants can download data to their device or access it via the cloud, and then assess it using a custom data analysis tool.
“With Exoplanet Watch you can learn how to observe exoplanets and do data analysis using software that actual NASA scientists use,” said Rob Zellem, the creator of Exoplanet Watch and an astrophysicist at NASA’s Jet Propulsion Laboratory in Southern California. “We’re excited to show more people how exoplanet science is really done.”
A planet passing in front of its parent star creates a drop in the star’s apparent brightness, called a transit.

Helping without a telescope
Participants without telescopes can help astronomers comb through data that’s already been taken. The project has 10 years of exoplanet observations, collected by a small ground-based telescope south of Tucson, Arizona.
This year, the project will start collecting additional data from two other telescopes at the Table Mountain facility in Southern California, which JPL manages.
These telescopes look at nearby stars and search for what scientists call exoplanet transits: regular dips in a star’s brightness caused by a planet passing between the star and Earth. Essentially, a transit is an observation of a planet’s silhouette against the bright glare of its star.
Multiple NASA telescopes look for exoplanet transits as a way to discover new planets, but Exoplanet Watch participants primarily observe transits by planets that have already been discovered to gain more information about their orbits.
The time between exoplanet transits reveals how long it takes an exoplanet to orbit its parent star; the more transits that are measured, the more precisely the length of the orbit is known.
If the timing of the orbit isn’t measured precisely, scientists who want to study those planets in more detail with large ground-based or space-based telescopes can lose valuable observing time while they wait for the planet to appear. Having volunteers sort through the data will save significant computing and processing time.
Exoplanet Watch participants will also look for variations in the apparent brightness of stars – changes caused by features such as flares (outbursts of light) and star spots (dark spots on a star’s surface). In transit measurements, these changes make a planet appear smaller or larger than it actually is. This work will help scientists anticipate the variability of a particular star before they study its exoplanets with large, sensitive telescopes like NASA’s James Webb Space Telescope.

Want to take your own data? Although the number of targets you can see increases with the size of the telescope used, there’s no minimum size requirement. For example, Exoplanet Watch can help you detect exoplanet transits for hundreds of nearby stars with just a 6-inch (15-centimeter) telescope.
Exoplanet Watch combines observations of the same target by multiple sky watchers in order to get a higher-fidelity measurement. Combining observations is also useful if the planet’s transit lasts longer than the time a star is visible in the sky for a single observer: Multiple participants at different locations around the globe can collectively watch the duration of a long transit.
That was the case with a planet called HD 80606 b, which Webb will observe this year. A recent study of this planet led by Kyle Pearson, the Exoplanet Watch deputy science lead at JPL, combined observations from more than 20 Exoplanet Watch participants.
The volunteer effort on HD 80606 b will free up almost two hours of time on Webb for other observations. And on missions that aim to observe hundreds or thousands of exoplanets, the number of minutes saved by refining planet transit measurements can add up and free a significant amount of observing time, according to Zellem.
One of the program’s policies requires that the first paper to make use of the observations or analysis done by volunteers will list those volunteers as co-authors, which was the case with the study led by Pearson. “I hope this program lowers barriers to science for a lot of people and inspires the next generation of astronomers to join our field,” said Zellem.
The ground-based data for the project was collected by the MicroObservatory Robotic Telescope Network, supported by NASA’s Universe of Learning and managed by the Center for Astrophysics | Harvard & Smithsonian in Cambridge, Massachusetts. Volunteer-generated data is uploaded to the American Association of Variable Star Observers’ (AAVSO) Exoplanet Database.
NASA’s Universe of Learning is a competitively selected member of the NASA Science Activation program. The Science Activation program connects NASA science experts and real content and experiences with community leaders to do science in ways that activate minds and promote deeper understanding of our world and beyond.

LAKEPORT, Calif. — A Lakeport man was arrested Sunday for a hit-and-run crash that injured a pedestrian.
Al James, 63, was arrested at about 10 a.m. Sunday, the Lakeport Police Department said.
Police officers were dispatched to the scene of a crash involving a vehicle and a pedestrian at a location on N. Main Street just before 6 p.m. Saturday evening.
The driver had fled the scene prior to the arrival of officers, authorities said.
The elderly female pedestrian, who was conscious and alert at the scene, was transported to Sutter Lakeside Hospital.
Police later reported that she was transported by air ambulance to an out-of-county hospital where she is recovering.
The only witnesses at the scene pointed law enforcement to a silver-colored larger SUV vehicle which was seen driving northbound on N. Main Street near the crash scene at the time of the collision.
On Sunday, police said they had apprehended James, originally a Texas resident.
He was booked into the Lake County Jail for felony hit-and-run, with bail set at $10,000.
Jail records indicated he was no longer in custody on Sunday night.

The National Weather Service’s forecast shows heavy rain through Thursday, Jan. 19, 2023. LAKE COUNTY, Calif. — Forecasters said that Lake County could receive several more inches of rain in coming days as the last atmospheric river storms in a series move over the region.
The National Weather Service’s six-day forecast released on Friday and continuing until Thursday, Jan. 19, called for up to 7 inches of rain.
That’s a concern for areas of Lake County including Upper Lake, where residents on Main Street near Maddocks Court were seeing full culverts and water covering portions of the roadway late this week, leading to them placing sandbags and using fire hose to try to move water away from homes.
State Climatologist Dr. Michael Anderson said the storm on Friday was the end of the seventh atmospheric river storm in a series that began hitting California at Christmas.
He said the eighth storm will take place from Saturday through Tuesday, Jan. 17, to be followed by the ninth storm on Wednesday, Jan. 18.
Anderson said high pressure is building in the eastern Pacific, and rather than storms coming ashore from the southwest or the west, storms will start dropping in from the Gulf of Alaska. Those storms will be colder, with not as much moisture.
Early Saturday, Clear Lake’s level was at 2.54 feet Rumsey, the special measure for the lake, up nearly 5 feet since Christmas.
Due to the atmospheric river storm event’s continued impacts on Lake County, on Thursday, Sheriff Rob Howe declared a local emergency.
The Lake County Office of Emergency Services said Friday on its Facebook page that Sheriff Howe sent his thanks and appreciation to the California Highway Patrol’s Northern California Division for conducting aerial reconnaissance of remote areas of Lake County to assess the potential impacts of the atmospheric river event.
“The Lake County Office of Emergency Services and Sheriff’s Office continue to monitor the condition of our county during this storm event,” the agency said.
During a special Friday afternoon meeting of the Board of Supervisors, Lt. Gavin Wells, the deputy director of Lake County OES, presented Howe’s emergency proclamation to the board for ratification, which needed to take place within seven days of its issuance.
Wells said the state has declared an emergency due to the storms and Lake County was included in a federal declaration for disaster assistance for counties issued on Jan. 9.
The board voted unanimously to ratify the proclamation.
