Stanislaus County Parks & Recreation will no longer manage Woodward Reservoir after October 2026, following a decision by the South San Joaquin Irrigation District (SSJID) to end its license agreement with the county. The SSJID board voted unanimously to serve a one-year notice, citing unresolved negotiations over park operations and financial management.
The transition means Stanislaus County will continue to operate the regional park for another year. After that, SSJID or a recreation contractor will take over management of activities at Woodward Reservoir, which has historically included camping, fishing, picnics, water sports, and large events such as concerts and festivals.
According to SSJID General Manager Peter Rietkerk, “SSJID has thoroughly reviewed the operations at Woodward Reservoir and determined that our district is best positioned to guide its future. We are committed to ensuring the transition delivers clear benefits for our ratepayers and reservoir users.”
SSJID stated that the change aims to improve oversight of recreational activities while prioritizing water quality in the 2,900-acre lake. The reservoir serves as a drinking water source for several cities in San Joaquin County. Some activities like swimming are restricted during certain periods due to these concerns.
During the upcoming transition period, both agencies plan to coordinate efforts to maintain public access and address operational needs while focusing on protecting water quality. In the fiscal year ending in 2024, Woodward regional park recorded about 482,000 visits.
Discussions between SSJID and Stanislaus County have been ongoing since 2022 regarding transparency in operations and finances related to the park. Amendments made in 2005 required further negotiation starting in late 2022; however, talks stalled particularly around revenue and expense issues.
A spokesperson for Stanislaus County confirmed receipt of the formal termination notice from SSJID and said the county is reviewing official materials. In a statement, county officials said: “Woodward Reservoir has been a valued part of Stanislaus County’s park system and a regional recreation destination for decades. The county appreciates the partnership with SSJID that has allowed generations of residents and visitors to enjoy this public asset safely and responsibly.” They added: “While today’s developments were unexpected and disappointing, Stanislaus County remains hopeful that future discussions with SSJID will focus on ensuring a smooth and coordinated transition that protects water quality, maintains public access and serves the best interests of our community.”
SSJID spokesperson Katie Patterson indicated recreational options at Woodward will be evaluated during the next year. Management models under consideration include direct district oversight or hiring an outside contractor for recreation services.
Patterson also addressed concerns about invasive golden mussels discovered in nearby waterways late last year; boating was temporarily halted at Woodward as a precaution against their spread. She noted communication issues between agencies regarding boating policy changes and emphasized that an infestation could lead to severe consequences such as draining the reservoir—a critical source for agricultural customers and local cities.
Effective October 1st, boats launching at Woodward (and Modesto Reservoir) must comply with quarantine procedures designed to prevent invasive species introduction.
Patterson said deteriorating facilities like bathrooms contributed to declining reputation based on social media feedback: “It was a myriad of reasons over the last few years that caused our board to believe a management change needs to happen,” she said.
Carissa Lucas from Stanislaus County stated she could not comment on invasive mussel issues without consulting parks leadership but noted discrepancies in materials provided by SSJID regarding agency collaboration.
Lucas said: “We look forward to addressing these matters directly with the district.”
The transitional period may also involve property negotiations because some parcels around Woodward are owned by Stanislaus County despite overall reservoir ownership resting with SSJID.
Separately, Stanislaus County Parks & Recreation continues managing Modesto Reservoir Regional Park while working on plans for Turlock Lake State Recreation Area restoration.
