Press release from the Trinity River Restoration Program:

The Bureau of Reclamation’s Trinity River Restoration Program (TRRP) is inviting individuals and organizations to comment on its draft Environmental Assessment (EA) to shift some of the water typically released from Lewiston Dam in late spring to the winter and early spring period.

Starting in winter 2021-2022, Reclamation’s TRRP proposes to change how annual Trinity River water is managed to benefit Trinity River fisheries. Moving a portion of Trinity River water volume to the winter and spring run-off periods is proposed to better match natural flow variability within the watershed.

Expected benefits of the proposal would:

1) Enhance natural cleaning and transport of river gravels;

2) Limit the impact of cold water from the dam on growth of juvenile salmon and steelhead, as well as other native aquatic species;

3) Allow the river to naturally warm earlier in the season to better provide outmigration cues to migratory fish; and

4) Elevate flows before salmon emergence from their in-river nests (redds) to increase food availability and access to floodplain nursery habitats.

The draft Winter Flow Variability EA was prepared in accordance with the National Environmental Policy Act and is available at the USBR California Great Basin website: https://www.usbr.gov/mp/nepa/nepa_project_details.php?Project_ID=50427) or at the TRRP website https://www.trrp.net/restoration/flows/winter-flow-variability/.

A public comment meeting, held virtually, will take place on Tuesday, October 5, 2021 at
6 p.m.
A link to the meeting will be available on the TRRP website – Winter Flow Variability page: https://www.trrp.net/restoration/flows/winter-flow-variability/. Written comments are due by close of business October 18, 2021. Comments may be emailed to [email protected], or mailed to Winter Flow Variability Project, C/O Bureau of Reclamation, Trinity River Restoration Program, P.O. Box 1300, Weaverville, CA 96093.

How about stop pumping it over to Whiskey Town lake.

And get rid of the dams. Nothing they have tried since the dams were built in 1962 has worked.

Water isn’t pumped to Whiskeytown, it flows downhill through a pair of tunnels in the mountain to Carr Powerhouse, which dumps into Whiskeytown Reservoir, then flows downhill to Keswick Powerhouse, dumping into the Sacramento River. The project generates electricity which is sold to public utilities, who sell it to consumers.
Water is sold to farmers and municipalities all down the Sacramento Valley. Water is then pumped “uphill” From Tracy to the Grapevine, and up and over the Tehachapi’s to LA.
Doesn’t that give you a warm and fuzzy feeling?
How about taking out Trinity and Lewiston dams and opening up miles of fish habitat that salmon used to use for spawning and rearing?

The trinity is the only river for miles and miles ,besides the Sacramento, with fish in it. It is all thanks to the dam.

Neither of the claims you are making are true.
