2022-2023 Engineer’s Report on the Groundwater Conditions, Water Supply and Basin Utilization in the Orange County Water District

Orange County Water District (OCWD) | February 21st, 2024

Total water demands within Orange County Water District (OCWD) were 351,719 acre feet (AF) for the 2022-23 water year (beginning on July 1, 2022 and ending on June 30, 20

Total water demands within Orange County Water District (OCWD) were 351,719 acre feet (AF) for the 2022-23 water year (beginning on July 1, 2022 and ending on June 30, 2023). Groundwater production for the water year totaled 245,210 AF including any available In-Lieu Program water. The use of supplemental water in OCWD’s service area during the 2022-23 water year totaled 107,723 AF of which 88,441 AF resulted from the direct use by water agencies and districts and 19,282 AF were used for the purpose of groundwater basin replenishment and maintenance of seawater intrusion control barriers. For the water year which ended on June 30, 2023, the “annual overdraft” (annual basin storage decrease without supplemental replenishment water) was 52,250 AF. The accumulated overdraft decreased from 258,000 AF on June 30, 2022 to 189,000 AF on June 30, 2023. Precipitation within the groundwater basin was one hundred fifty eight percent of the long-term average during this water year, totaling 21.12 inches. Based on the groundwater basin conditions for the water year ending on June 30, 2023, OCWD may purchase up to 123,000 AF of water for groundwater replenishment during the ensuing water year, beginning on July 1, 2024, pursuant to the District Act.

2022 was a year of visible progress and momentum for the Salton Sea Management Program (SSMP) and partners. The first large-scale restoration project in the Sea’s history achieved major construction milestones, while community-oriented projects and vegetation enhancement made headway around the Sea in collaboration with state, federal and local entities.

2023 Annual Water Supply and Demand Assessment Summary Report

This annual report summarizes the Department of Water Resources’ (DWR’s) review of Urban Water Suppliers’ Annual Water Shortage Assessment Reports (Annual Shortage Reports) for the State Water Resources Control Board (State Water Board). As directed by the California Water Code (CWC) §10644(c)(1)(B), this summary report includes water shortage information at the supplier level, as well as regional and statewide analyses of water supply conditions.

2023 Drinking Water Needs Assessment

The Needs Assessment is comprised of four core components: the Failing Water System List (Failing list), the Risk Assessment, the Cost Assessment, and the Affordability Assessment. Public input that the State Water Board received via workshops held in 2022 and February 2023 helped improve the 2023 Needs Assessment.

2024 5-Year Review: Summary & Evaluation of Northern California Steelhead

National Oceanic and Atmospheric Administration (NOAA) | July 9th, 2024

Many West Coast salmon and steelhead (Oncorhynchus spp.) stocks have declined substantially from their historic numbers and now are at a fraction of their historical abun

Many West Coast salmon and steelhead (Oncorhynchus spp.) stocks have declined substantially from their historic numbers and now are at a fraction of their historical abundance. Several factors contribute to these declines, including: overfishing, loss of freshwater and estuarine habitat, hydropower development, poor ocean conditions, and hatchery practices. These factors collectively led to the National Marine Fisheries Service’s (NMFS) listing of 28 salmon and steelhead stocks in California, Idaho, Oregon, and Washington under the Federal Endangered Species Act (ESA). The ESA, under section 4(c)(2), directs the Secretary of Commerce to review the listing classification of threatened and endangered species at least once every 5 years. A 5-year review is a periodic analysis of a species’ status conducted to ensure that the listing classification of a species as threatened or endangered on the List of Endangered and Threatened Wildlife and Plants (List) (50 CFR 17.11 – 17.12; 50 CFR 223.102, 224.101) is accurate (USFWS and NMFS 2006; NMFS 2020). After completing this review, the Secretary must determine if any species should: (1) be removed from the list; (2) have its status changed from endangered to threatened; or (3) have its status changed from threatened to endangered. If, in the 5-year review, a change in classification is recommended, the recommended change will be further considered in a separate rule-making process. The most recent 5-year review analysis for West Coast salmon and steelhead occurred in 2016. This document describes the results of the 2024 review of ESA-listed Northern California steelhead (NC steelhead). A 5-year review is: • A summary and analysis of available information on a given species; • The tracking of a species’ progress toward recovery; • The recording of the deliberative process used to make a recommendation on whether or not to reclassify a species; • A recommendation on whether reclassification of the species is indicated.

2024 Annual Multibenefit Land Repurposing Program Report

The Multibenefit Land Repurposing Program (MLRP) increases regional capacity for repurposing irrigated agricultural land to uses that reduce reliance on groundwater while providing community health, economic well-being, water supply, habitat, renewable energy, and climate benefits. The program provides funding for regional block grants, tribal grants, and a Statewide Support Entity to provide technical assistance to block grantees and support progress toward program goals.

Significant, measurable progress continued at the Salton Sea (Sea) over the last year. The largest restoration project in the Sea’s history neared completion, suppressing dust and restoring habitat across thousands of acres at the south end of the Sea. In other areas along the Sea, hundreds of acres now host native vegetation recently planted to suppress dust over coming decades. These plants have taken root, are growing and are beginning to serve their purpose. This year also witnessed the first major investment by federal agencies to stabilize the Sea; the U.S. Bureau of Reclamation (Reclamation) granted $70 million to accelerate local restoration projects.
