PG&E’s conducting flow gate tests on Pit 5 this Tuesday, which not only means high water that day, but likely unsettled fishing.
From PG&E:
Pacific Gas and Electric Company (PG&E) has rescheduled to Tuesday, Oct. 11 an increased flow test on the Pit River below the Pit 5 Diversion Dam. The test was originally scheduled for Monday, Oct. 3.
PG&E is conducting a regular test of dam flow gates, which is required by the Federal Energy Regulatory Commission. The test is being done on a weekday in the fall when recreational use of the river is low and before winter rains increase river flows. Water levels will rise about half a foot an hour for about six to eight hours, starting before dawn so that the river stops rising before sunrise.
The increased flows will not be noticeable beyond the Pit 6 Dam. This portion of the Pit River is remote with no established recreational facilities.
The higher flows will not exceed those experienced in fall and winter.
The maximum flow of 1,800 cubic feet per second (cfs) will be held for about six to eight hours, then gradually reduced over a period of about six to eight hours until all gates are closed.The anticipated flow before and after testing will be 350 cfs.

Robert Lusardi is the California Trout/UC Davis Wild and Coldwater Fish Researcher focused on establishing the basis for long-term science specific to California Trout’s wild and coldwater fish initiatives. His work bridges the widening gap between academic science and applied conservation policy, ensuring that rapidly developing science informs conservation projects throughout California. Dr. Lusardi resides at the UC Davis Center for Watershed Sciences and works closely with Dr. Peter Moyle on numerous projects to help inform California Trout conservation policy. His recent research interests include Coho salmon on the Shasta River, the ecology of volcanic spring-fed rivers, inland trout conservation and management, and policy implications of trap and haul programs for anadromous fishes in California.
Patrick Samuel is the Conservation Program Coordinator for California Trout, a position he has held for almost two years, where he coordinates special research projects for California Trout, including the State of the Salmonids report. Prior to joining CalTrout, he worked with the Fisheries Leadership & Sustainability Forum, a non-profit that supports the eight federal regional fishery management councils around the country. Patrick got his start in fisheries as an undergraduate intern with NOAA Fisheries Protected Resources Division in Sacramento, and in his first field job as a crew member of the California Department of Fish & Wildlife’s Wild and Heritage Trout Program.
