Spring releases to rev up beginning Saturday
The Trinity River will be flowing high in a few days as releases from Lewiston Dam rise to hit a spring high flow of 11,000 cubic feet per second after a determination that this is an “extremely wet” year for the basin.
People residing near the river or recreating on the river can expect river levels to increase and should take appropriate safety precautions. Landowners are advised to clear personal items from the floodplain prior to the releases.
Based on a forecast inflow to the Trinity and Lewiston reservoirs of 2,265,000 acre-feet from Oct. 1, 2016, through Sept. 30, 2017, this has been determined to be an “extremely wet” year for the Trinity River basin.
Under the Trinity River Record of Decision, in an extremely wet year 815,000 acre-feet of water is to be released from Lewiston Dam to the Trinity River over the course of the year for fisheries.
Normally at this point the release is 300 cfs although recently it was 1,500 cfs for reservoir storage management.
Under the flow schedule:
► On April 22 the release will quickly ramp up for the spring high flow.
► On April 26 the release reaches 11,000 cfs and remains at that level through April 29.
► After April 29 the release drops to reach 2,050 cfs on May 7, then climbs again for a second, smaller peak.
► On May 11 the release reaches 5,400 cfs where it remains to June 4, then begins a gradual drop.
► On Aug. 11 the release reaches the summer base flow of 450 cfs.
