Western Weather Group reported rain levels approaching 2 inches on Monday for many areas of Lake County, with Middletown nearing 3 inches and one weather station in the Red Hills area between Kelseyville and Lower Lake showing approximately 3.55 inches.
US Geological Survey stream gauges showed the levels in area streams and creeks jumped thanks to the recent storms.
Clear Lake was reported to be at 1.23 feet Rumsey late Monday, up from less than 0.80 feet Rumsey earlier in the week.
The Lake County Sheriff's Office of Emergency Services warned that there could be instances of flooding later in the week. But that problem already had started Monday afternoon, when the CHP reported water over the roadway on Highway 20 just west of Lucerne.
One area that was hit particularly hard by Monday's storms was Cobb.
Cobb resident Roger Kinney said they were experiencing gusting winds and power outages, along with several small hailstorms.
They also had several thunderstorms, Kinney said, with the thunder and lightning getting so close at one point that it was shaking his house.
Around the rest of the county, there were numerous instances of trees that were down and blocking roadways and downed power lines.
Shortly before 2 p.m. officials reported downed power lines blocking both lanes on Bottle Rock Road north of Sulphur Creek, with South Lake County Fire Protection District and the California Highway Patrol responding.
Rock slides and boulders rolling onto area roads because of the saturated earth also were an issue.
One CHP report made shortly before 1 p.m. on Highway 29 near Lower Lake said there were rocks in the roadway “about the size of basketballs.”
Numerous car collisions – most without injuries – were reported Monday, with most appearing to be due to the wet conditions.
A crash that occurred at around 6 p.m. on Highway 29 just south of Spruce Grove Road resulted when a Ford Explorer hit a boulder that had gone into the roadway, according to the California Highway Patrol.
Monday evening, icy conditions were reported on Highway 53, and similar icy conditions on Highway 29 at Red Hills Road caused a vehicle to go off the roadway at around 9 p.m. No injuries were reported.
On Monday evening, a retaining wall on Beryl Way in Clearlake Oaks collapsed due to excessive water, which pushed cinder blocks from the wall into the road, according to the CHP.
The county's road department reported that Berle Way was scheduled to be closed until Tuesday morning because of the wall failure.
