Important Water Supply Update


February 20, 2018



  1. On Thursday, February 15th, 2018, the United States Bureau of Reclamation (USBR) notified CCID that based on DWR’s February 1st forecasted full natural inflow to Shasta Lake, that the 2018 Year is currently not a Critical Water Year under the Exchange Contract.
  2. USBR will be updating the forecast and allocation to us monthly over the next few months.
  3. CAUTION: Additional modelling conducted by the NOAA River Forecast Center (RFC) indicates that if the current extreme dry hydrology continues, then projected inflow into Shasta could drop enough to cause the USBR to change our allocation to a Critical Water Year. That would reduce our 2018 water supply by approximately 25%.


  1. The 2018 Water Rates and Tier pricing will remain in effect as outlined in our January 30, 2018 Water Supply Information Letter to Consumers unless the allocation changes.
  2. Please continue to be cautious with your water usage, keeping in mind that there is a chance based on the forecasts that your water supply could get reduced to critical levels, an approximate 25% reduction.

This information is based on the current information available to us. Each water user must make their own individual risk assessment, and decide when and how much to plant and irrigate.

We are working diligently on your behalf. Please understand that things can change quickly and that we will update you as often as necessary so that you can make informed decisions.
