A series of moderate-sized earthquakes and powerful aftershocks hit near the California-Nevada border early Wednesday morning.

The United States Geological Survey reported that the series of quakes started at approximately 12:18 a.m. Wednesday with a 5.7-magnitude quake near Hawthorne, Nev., which was followed four minutes later by another quake of the same magnitude a short distance away.

Both of those quakes each received more than 1,000 shake reports as of 3 a.m. from more than 230 zip codes around central and Northern California and Nevada, the survey said.

Those initial quakes were followed over the next hour by a series of aftershocks measuring between 2.8 and 4 magnitude in Nevada and just across the California state border, according to US Geological Survey records.

At 1:13 a.m., a 5.5-magnitude quake was reported near the epicenter of the two larger quakes, and over the next two hours was followed by another series of aftershocks on both sides of the state border that had magnitudes ranging from 2.5 to 3.2, the survey said.

That 5.5-magnitude quake received nearly 900 shake reports from 243 zip codes, according to survey records.

The California Department of Water Resources will conduct its first media-oriented manual snow survey of Water Year 2017 at 11 a.m. on Jan. 3 at Phillips Station, just off Highway 50 near Sierra-at-Tahoe Road approximately 90 miles east of Sacramento.

Electronic readings of the Sierra Nevada mountain snowpack on Tuesday peg its statewide water content at 10.5 inches, 72 percent of the December 27 average.
 
The Phillips snow course, which has been measured each winter since 1941, is one of dozens that will be traversed during a 10-day period around Jan. 1 to determine the water content of the snowpack, which normally contributes about 30 percent of California’s water when it melts. Manual readings supplement the Department of Water Resources' electronic data.

It’s too soon to know whether this winter’s wet season will deliver enough rain and snow to move California closer to the end of the state’s five-year drought.

The snowpack usually is at its deepest and most water-laden around April 1, so weather watchers won’t know with certainty what kind of wet season it has been until then.

Water Year 2017 began with above-average rainfall in October in all three Sierra Nevada regions monitored continuously by DWR.

Northern California’s wettest Oct. in 30 years sparked optimism for a robust water year. November saw below-average precipitation in all three regions, but wet weather returned in December and produced above-average rainfall in the three regions.

Rainfall measured from Oct. 1 through Dec. 27 at the department's 19 key monitoring stations totaled 150 percent of the stations’ combined historical average during that period.

As the three traditionally wettest months of the year began on Dec. 1, the statewide snowpack’s water content was just 61 percent of average on that date.

Relatively warm temperatures had tended to produce rain rather than snow in the mountains, but the cold storm that arrived last weekend improved the snowpack up to 75 percent of the Christmas Day average.

The snowpack on Tuesday held at 72 percent of the Dec. 27 average water content.

California is three months into what could become its sixth consecutive year of drought. State Climatologist Michael Anderson said, “October was one of our wettest on record, and December has produced a nice rebound from November’s below-average precipitation. California needs sustained above-average precipitation and a decent snowpack to overcome the previous years of drought.”

Statewide snowpack water content – Jan. 1 average (10.2 inches):
                   
• 2002 – 162 percent;
• 2003 – 162 percent;
• 2004 – 142 percent;
• 2005 – 159 percent;
• 2006 – 117 percent;
• 2007 – 61 percent;
• 2008 – 59 percent;
• 2009 – 78 percent;
• 2010 – 87 percent;
• 2011 – 209 percent;
• 2012 – 20 percent;
• 2013 – 137 percent;
• 2014 – 20 percent;
• 2015 – 47 percent;
• 2016 – 103 percent.

LAKE COUNTY, Calif. – While Lake County didn't have a white Christmas, parts of the county could see both rain and snow just after the start of the new year.

The National Weather Service is predicting chances of snow on Monday, Monday night and into Tuesday in parts of Northern California including Lake County.

The agency said slightly warmer weather is expected across Northern California over the next few days, with clear conditions and daytime temperatures in Lake County ranging in the high 50s and low 30s at night.

On Friday night and Saturday there are chances of rain, with rain also possible on New Year's Day and night, according to the forecast.

Forecasters expect the next push of cold Arctic air to arrive early next week, pushing from western Canada into Northern California and bringing with it the possibility of low elevation snow.

The specific Lake County forecast calls for daytime temperatures to drop into the low 40s beginning on Monday, when there are chances of both rain and snow around the lake.

Nighttime temperatures are expected to dip below freezing, with chances of snow also forecast on Monday night and during the day on Tuesday.

Forecasters said to stay tuned as they get a better idea of what the weather system may bring to Northern California.

NORTH COAST, Calif. – The North Coast Regional Water Quality Control Board assessed a $37,079 penalty for a Clean Water Act violation against the owners of a Mendocino County property at the Board’s December meeting.

The penalty is for discharges of sediment-laden water into a tributary of the Upper Main Eel River.

The discharge was caused by the failure of a 50,000 gallon fuel bladder being used for water storage allegedly for fire protection.

Polly Franklin, trustee for the property trust, and her son, Daniel Franklin, were named in the violation order.

According to testimony at the enforcement hearing during the Regional Water Board’s December meeting, the storage bladder was overfilled, causing it to burst.

A minimum of 50,000 gallons of water were discharged, flowing over and through an adjacent earthen berm, and entering a small watercourse.

The water traveled 2,000 feet downstream, tearing out riparian vegetation, stripping away instream soil, rocks and boulders, and eventually entering the Upper Main Eel River.

Staff of the California Department of Fish and Wildlife reported seeing increased turbidity for at least a day and a half following the incident, and a high rate of fish outmigration.

The effects were observed more than three miles downstream in the Eel River at the Van Arsdale fish station.

Staff of the Regional Water Board, California Department of Fish and Wildlife, and the California Geologic Survey inspected the site following the event, and documented the damage throughout the segment of the watercourse from the discharge point down to the Upper Main Eel River.

The Regional Water Board adopted the order assessing a penalty of $37,079 against Polly Franklin as trustee of the trust that owns the property, and Daniel Franklin as the person responsible for activities that occurred on the property resulting in the unauthorized discharge. 

The board found that the discharge posed a significant threat of harm to beneficial uses. The board noted that while the bladder failure was not intentional, it was negligent.

Regional Water Board staff note that storage bladders, both new and military surplus, are widely available and often used for water storage throughout the North Coast Region. 

However, many bladders are not specifically designed to hold water, have a limited service life, and are susceptible to failure due to overfilling or puncture by external causes.

Water releases from ruptured storage bladders may cause significant erosion, instream damage and harm to aquatic species and habitat.

Staff encourages those individuals selling or purchasing storage bladders and/or collapsible fabric tanks to make themselves familiar with limitations and cautions associated with their specific bladders, and to take care in siting, installing, operating and maintaining storage bladders to minimize the potential for failure and abrupt release of water into nearby streams.
