Surface Water Diversion (Notification of Lake or Streambed Alteration, No. EPIMS-TRI-55891-R1)

The California Department of Fish and Wildlife has authorized a domestic water diversion project under Lake and Streambed Alteration Agreement EPIMS-TRI-55891-R1, permitting Heather O’Connell to install and operate a non-impounding diversion structure in a spring-fed tributary to Grub Gulch near Weaverville, California. The system consists of a buried perforated PVC barrier dam with two one-inch intake pipes and one one-inch overflow pipe, designed to channel water via a three-quarter-inch polyline by gravity to a parcel located just west of the project site. Operation is strictly regulated by Water Right A026786, with seasonal flow limits: 80 gallons per day from June 1 through September 20 and 40 gallons per day from October 1 through May 31. The structure is engineered to allow natural streamflow over its top, ensuring no ponding or obstruction, and qualifies for a categorical exemption under California Code of Regulations Title 14, Section 15303, due to its minor, non-hazardous nature and minimal environmental impact. All work must conform to the Fish and Game Code Section 1602, and no impoundment or alteration of natural flow is permitted. The project is not a federal contract and does not involve standardized Federal Acquisition Regulation clauses, procurement processes, or financial terms. It is a regulatory compliance notification approved under state authority, with no solicitation, competitive bidding, or contract value established. The approval is administered by the CDFW Region 1 Northern Office, with oversight handled by environmental scientists and habitat program managers responsible for ensuring compliance with CEQA and water rights conditions. There is no formal payment mechanism, invoicing process, contracting officer, or technical representative assigned under federal models, and no socioeconomic, size, or entity certifications are required or provided. Performance is defined by adherence to seasonal flow rates, structural specifications, and the absence of streambed obstruction, with acceptance contingent upon regulatory compliance rather than formal inspection or delivery protocols. The location is legally described as Section 10, Township 33N, Range 10W, Mt. Diablo Base and Meridian, with a physical address at 161 Shasta View Lane, Weaverville, CA 96093.
