This Request for Proposals is being issued to interested parties who wish to be considered for selection to provide professional engineering consulting services to the Colusa Groundwater Authority (CGA) to support the justification and collection of a benefit assessment for the day to day operations of the CGA. The CGA is looking for a highly qualified assessment engineer team that is familiar with the Sustainable Groundwater Management Act, as well as the requirements of Proposition 218.
On Friday, May 18, the CA Department of Water Resources released the draft prioritization of groundwater basins as required by the Sustainable Groundwater Management Act (SGMA). The 2018 SGMA Basin Prioritization is scheduled to be finalized by fall 2018 after a 60 day public comment period that starts today and runs through July 18, 2018.

ATTENTION ALL USERS OF GROUNDWATER WELLS IN COLUSA, AND/OR GLENN COUNTY:
The State of California under the Sustainable Groundwater Management Act (SGMA) law requires all groundwater well users to live under a Groundwater Sustainability Plan developed by Groundwater Sustainability Agencies that must be completed by January 31, 2022. This Plan will require all groundwater well use to be sustainable for all parts of the basins throughout California, and will potentially require meters and records on groundwater use. Also required will be a plan for recharging the aquifers if groundwater falls into an overdraft situation.
Development of the Groundwater Sustainability Plans by Groundwater Sustainability Agencies is just getting underway in Colusa and Glenn Counties. Each groundwater user has the opportunity to help develop these Plans which all users will have to live by. It would behoove all groundwater users to get involved in this process.
Please attend Groundwater Sustainability Agency meetings and other local water management meetings including the Colusa Groundwater Authority, Glenn Groundwater Authority, and Colusa County Groundwater Commission meetings, and add your name to email notification lists.

The Sustainable Groundwater Management Act (SGMA) established a process for local Groundwater Sustainability Agencies (GSAs) to request that the California Department of Water Resources (DWR) revise the boundaries of a groundwater basin or subbasin in order to promote sustainable groundwater management.
The CGA intends to submit a request to DWR for a Basin Boundary Modification (BBM) by June 30, 2018. This modification would bring the Colusa County portion of the West Butte Subbasin that lies on the west side of Reclamation District 1004 into the Colusa Subbasin.
The CGA is interested in receiving feedback from local agencies and landowners. Click HERE for more information.
