Kern River Status Update
Lake Isabella has received 3.38″ of precipitation since October 1, 2020. With the low DWR forecast (see below) Utility and State Water Project (SWP) water for the Kern Island, Buena Vista, Stine, and Farmers service areas will be prorated over the summer. Estimated amounts for Utility and SWP prorations will be released after DWR publishes their April 1 Bulletin 120 forecast.
DWR released their March 1 Bulletin 120 (B-120) forecast for the 2021 April through July runoff of the Kern River. The March 1 forecast for this year is 29% of average. This forecast is based on observed conditions and physical measurements through the end of February and assumes normal precipitation after. Every day that there isn’t precipitation will cause the forecast to go down.
