Groundwater management is at the heart of conversations about sustainability, climate resilience, and water security in California. With the Consortium’s active role in groundwater-related projects, staff recently attended the seventh annual Western Groundwater Congress (WGC) hosted by the Groundwater Resources Association of California. This event brings together nongovernmental organizations, state agencies, government officials, consultants, and community groups to address critical issues in managing groundwater across the western United States. Held this year in Olympic Valley near Lake Tahoe, the WGC offered insights into the current state of groundwater in the west, recent innovations in water conservation, and strategies for long-term groundwater sustainability.

A Grounded Welcome

The event opened with a powerful welcome by Herman Fillmore, the Culture and Language Resources Director for the Wá∙šiw (Washoe) Tribe of Nevada and California. Fillmore shared the history of the region in the Wá∙šiw language and English, providing valuable context on local hydrology, conservation efforts, and the ongoing relationship between the land and its stewards. His remarks emphasized the deep connections between water, ecosystems, and the cultural and environmental heritage of the area—connections that continue to guide sustainable groundwater management practices today.

The Role of Data in Groundwater Management

A recurring theme throughout the conference was the importance of reliable data in improving groundwater management. Many sessions highlighted the need for digital transformation, enabling smarter, more effective decisions. Speakers emphasized how operational, social, and environmental data, scaled appropriately, can inform policies and foster better communication with partners. Reliable and trustworthy data not only guides action but also strengthens transparency and collaboration.

This aligns directly with the Consortium’s work on initiatives like the open-source Groundwater Accounting Platform, which empowers water managers with actionable data to meet the requirements of the Sustainable Groundwater Management Act. Tools like this help translate complex groundwater systems into clear, accessible information that informs better planning for agriculture, urban development, ecosystem health, and communities.

Olympic Valley Water District Tour

The conference concluded with a guided tour led by the Olympic Valley Public Service District (OVPSD). Participants explored the district’s innovative water system, which supplies well water to 44 commercial entities and approximately 1,600 residential homes. OVPSD staff shared insights into the district’s sustainable water policies, which date back to 1978, as well as strategies for managing their isolated aquifer in response to seasonal shifts and flood risks, like their supervisory control and data acquisition system (SCADA) and data management systems. Attendees learned about local hydrology, conservation practices, and the interconnectedness of plants, policies, and the surrounding environment.

The tour provided a powerful example of how community-level water systems can adapt to future challenges by integrating conservation policies and community collaboration, and how data is integral to this coordination. Transparent data and purpose-built tools enhance the efficiency of public service staff and foster alignment between governments and the communities they serve by informing policy decisions with reliable data.

 

Broader Implications for Groundwater Management

Groundwater is a shared resource that underpins not only California’s water security but also its agricultural productivity, urban development, and environmental health. The discussions at the WGC underscored how innovations in groundwater management—whether through advanced data tools or adaptive policy frameworks—are critical for addressing challenges like drought, population growth, and climate change.

The 2024 Western Groundwater Congress provided an inspiring forum for exploring the latest science, challenges, and policies shaping groundwater management in California. It was a powerful reminder of the Consortium’s critical role in helping to advance data-driven decisions that ensure groundwater sustainability. Hearing from experts about the value of reliable data and stewardship underscored the importance of the work being done to secure a resilient water future for all.
