The Trinity River Restoration Program will host a public informational meeting to present the recommended 2017 spring restoration flow releases from Lewiston Dam and gravel augmentation plans.
The meeting will be held from 6 to 7:30 p.m. Tuesday, April 11, at the restoration program office at 1313 S. Main St. in the Tops shopping center in Weaverville. Restoration program staff will be available to answer questions on the presentations.
Gravel augmentation is combined with the flow releases to replace gravel trapped by the upstream dams that is necessary for salmon habitats. The gravel is locally supplied from the Trinity River Basin.
Under the five water year types that the Program operates under, ranging from “critically dry” to “extremely wet,” a “wet” or “extremely wet” water year is likely for 2017. In a “wet” water year, 701,000 acre-feet of water is allocated for restoration flows, compared to an “extremely wet” water year when 815,000 acre-feet is allocated.
Under the two schedules, flows are expected to increase beginning on April 22 and reach their highest peaks either April 26 or May 10. The river could remain elevated as late as May 16.
