Water Resources Association of Yolo County

The Water Resources Association of Yolo County (WRA)  was formed in 1993 as a nonprofit mutual-benefit corporation with the specific purposes to (a) support the efforts of its members to obtain, protect, and maintain a high quality water supply adequate for the present and future needs of Yolo County; (b) educate its members, governmental authorities, and the public regarding all aspects of water use and water rights; and (c) provide a forum for the exchange of information between water purveyors.

For almost 30 years the WRA served a critical role in water resource planning in Yolo County, including serving as the lead agency in the development of the 2007 Yolo County Integrated Regional Water Management Plan (IRWMP), and as the region’s representative in the Westside Sacramento IRWM Group.

The WRA was actively engaged in the SGMA legislation and provided informational briefings for its member agencies and the general public throughout 2014 and was a leader in partnering with the Yolo County Farm Bureau, Yocha Dehe Wintun Nation, and other water agencies in Yolo County to form  the Yolo Subbasin Groundwater Agency (YSGA) in 2017.

When the YSGA was formed, the intention was to merge the WRA's purpose into the new agency. All of the former members of the WRA are also “Members” or “Affiliated Parties” of YSGA.  At the September 2022 WRA and YSGA  Board of Directors Meetings, the WRA Board voted to dissolve the WRA and the YSGA Board voted to take on the integrated water management role of the WRA. 

The Water Resources Association of Yolo County is dissolved, and the YSGA is now coordinating County-wide water resource management.
