The continuous flow from the Potter Valley Project changed the fish ecosystem in the Russian River by eliminating the warm, still pools that had been used for breeding by native fish. In the 1950s the state introduced poison to the river to eliminate "useless" fish species in favor of game species.
The resulting back-surge in water flow is expected to force X2 into the Delta, jeopardizing spatially oriented habitat (like freshwater marshes), channelizing the low salinity zone, and threatening southern California's water supply, with unknown and unforeseeable consequences for the natural and human ecology of the West coast's largest estuary.
The "flow regime" of a river or stream includes the general patterns of discharge over annual or decadal time scales, and may capture seasonal changes in flow. [7] [8] While water flow is strongly determined by slope, flowing waters can alter the general shape or direction of the stream bed, a characteristic also known as geomorphology. The ...
The Central Valley watershed, which incorporates the Sacramento River, San Joaquin River and Tulare Lake regions, is the largest in California, draining over a third of the state – 60,000 square miles (160,000 km 2) – and producing nearly half the total runoff.
Protecting the desert pupfish, listed as endangered since 1986, has been one of many vexing problems facing the Colorado River and the people and species that rely on it.
When altered flow regimes have impacted riparian zone health, re-establishing natural streamflow may be the best solution to effectively restore riparian ecosystems. [2] The complete removal of dams and flow-altering structures may be required to fully restore historic conditions, but this is not always realistic or feasible.
Watching the dark water flow past, Thompson said: “The river is healing. The river is clearing itself out.” The work of planting seeds in the empty reservoirs will continue this fall.
