The Big Valley Groundwater Advisory Committee convened on June 16 in Bieber, marking a significant gathering with representatives from both Lassen and Modoc counties attending together—an uncommon occurrence. Members of the Modoc County Resource Conservation District were also present.
The committee focused on various topics, including water sustainability, groundwater modeling, and support for residents with failing wells. Updates were provided on the Groundwater Sustainability Plan (GSP), which received approval from the California Department of Water Resources earlier this year after extensive revisions and negotiations.
A key discussion point was the Domestic Well Mitigation Program, aimed at assisting homeowners whose wells have gone dry due to declining groundwater levels. The program would offer resources such as bottled water, filling stations, and assistance with long-term solutions like deepening wells or connecting to community water systems. Approximately 15 permitted wells are currently deemed at risk. Homeowners would need to apply and demonstrate that their well failure is linked to groundwater issues rather than age or maintenance, with participation being voluntary.
Additionally, the committee considered applying for a temporary water rights permit to facilitate surface water use for recharge projects. This permit would enable water diversion from December to March at three designated locations, including Ash Creek and the Pitt River. The goal is to enhance groundwater supplies by moving water underground during wetter months. The final application for this permit is anticipated in July.
Progress is being made on a new groundwater model designed to predict trends and improve reporting accuracy. This model is being developed using historical well records, soil maps, satellite imagery, and local input. The committee stressed the importance of public engagement, urging farmers and residents to contribute information about irrigation practices and historical data.
Discussions also included the potential creation of a small community water system in Adin, with a study underway to assess demand and available water sources. A similar study is evaluating the feasibility of expanding Robert’s Reservoir and the long-discussed Allen Camp Dam project.
Public concerns were raised regarding water use data and the need for inclusivity of additional communities, such as Lookout. Committee members noted that West Yost, the firm responsible for groundwater planning, would provide follow-up reports in future meetings.
Water quality was another topic of discussion, with a voluntary test kit program being implemented for homeowners to check for nitrate and arsenic, common groundwater contaminants. While the kits are not lab-certified, they can provide basic readings for early detection.
The date for the next meeting will be announced, and information regarding the plan, along with recordings of past meetings, is accessible
