The lake wasdropping about a half-inch per day but the recent 2.14 inches of rain has caused the lake level to stop falling. It is now at 429.35 feet,10.65 feet below Glory Hole.

Lake capacity is at 87.4%

Surface temperature has dropped to 68 degrees from the surface to 10 feet down. The chart shows that mixing has begun. The lake is moving towards "turnover" when cold weather, wind, and rain will mix the lake to the same temperature from top to bottom.

The KPIX Eye on the Bay interview below is one I did in 2010 and a relevant introduction to the substance of the book. I did it after Pensus had been given the contract for 5 resorts. As we all know Pensus was subsequently kicked out in 2012.

Lake Berryessa Data Sources

There are many sources of Lake Berryessa water and weather conditions available. The Solano County Water Agency site is good for real-time graphs of level, capacity, and water temperature. The California Data Exchange Center has data going back decades for level, capacity, capacity change, dam outflow, dam inflow, and rainfall. Anyone can research their own data and create custom charts. This is the source of many of the charts on the Lake Berryessa News website.

********
An upgraded wildfire alert camera system will be keeping watch on Napa County day and night and notifying Cal Fire crews of potential fires. Twenty cameras will be part of a system that will use artificial intelligence and other technologies to identify fire and smoke. If they detect something, an alert will sound in the Cal Fire emergency command center near St. Helena.

Cal Fire has made a large investment into the ALERTCalifornia system, partnering with UC San Diego. There are 1,000 cameras across the state and Napa County is one of the test models. Cameras can see 60 miles during the day, and this can increase to 120 miles on clear nights, with the changes in the air. The system can differentiate among smoke, clouds and dust. A link to this camera system and other relevant weather data is available on the Lake Berryessa News website at: http://www.rntl.net/lake-berryessa-cams/

This website was created by Doug Kunst. It is an amazing resource for Lake Berryessa fire cameras and weather. His business website is http://www.rntl.net/
