2022 Water Supplies
LABEL
RECOMMENDED ACTION:
Recommendation
Receive a report on water supplies for 2022 drought year and determine that the action is exempt from CEQA.
Body
DISCUSSION:
Due to critically dry conditions both locally and throughout the state, available water resources were sparse in 2021 and drought conditions persist in 2022.
The City's main local supply of water, Lake Hennessey, received 19 inches of rain compared to our annual average of 27 inches. Lake Hennessey reached a low of 55% in October 2021 and is currently at 84% capacity, holding 26,080 AF as of April 18th. Milliken Reservoir is at 100% capacity, but it is much smaller, holding 1,400 AF.
In addition to the City's local supplies, the City contracts through the Napa County Flood Control and Water Conservation District (NCFCWCD) for water supply from the Department of Water Resources (DWR) State Water Project (SWP). Due to the limited precipitation throughout California and low Sierra snowpack, the SWP allocation is just 15% for North of Delta contractors. As a result, City of Napa will receive just 3,285 AF of our 21,900 AF of Table A entitlements this year in addition to 642 AF of Article 21 water. It is expected that 3,772 AF of Advanced Table A (ATA) water will be available this year. Total supplies from the SWP will be 7,699 AF.
In preparation for the uncertain water supply year in 2022-23, the City maintains it's goal to preserve local storage in Lake Hennessey at 60% as we enter the rainy season on Nov 1st.
On May 4, and June 1, 2021, City Council authorized the purchase of up to 3,442 AF of dry year water in an amount not to exceed $1,555,000. The City purchased five types of water: 109 AF of Dry Year Transfer Program (DYTP) at $665/AF, 304 AF Yuba Accord (Tiers 1,3) at $447/AF, 115 AF Yuba Accord (...
