Jackisch Water Diversion and Reservoir Spillway Improvements Project (Notification of Lake or Streambed Alteration, No. EPIMS-MEN-32979-R1C)

The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement EPIMS-MEN-32979-R1C with Scott Jackisch for the Jackisch Water Diversion and Reservoir Spillway Improvements Project in Willits, California. Pursuant to Section 1602 of the Fish and Game Code and Small Domestic Use Registration No. D033333, the project is limited to two encroachments for domestic use. The first involves the operation, maintenance, and modification of water diversion infrastructure from a horizontal well spring. The second involves water diversion from an onstream pond for domestic use and irrigation, including the installation of bypass infrastructure and spillway improvements. These improvements consist of excavation, the removal of a 24-inch diameter culvert, and the installation of an upgraded spillway with specific rock sizing and armoring to mitigate downstream erosion below a footbridge. The project is classified as a forecast with NAICS code 237990 and is granted a Class 1 Categorical Exemption under California Code of Regulations title 14, section 15301, as it involves the maintenance of private structures without expanding existing use. Regulatory oversight is provided by the California Department of Fish and Wildlife, Region 1, with Environmental Scientist Jessica Ryan serving as the primary point of contact. While the project is listed with a posted date of August 4, 2025, there are no specified contract values, formal procurement clauses, or defined periods of performance provided in the documentation.
