Steelhead Incubation: “We Dodged a Bullet”

Posted on Thursday, April 2nd, 2015

The results of recent field work indicate that the recent hot spell has NOT been lethal to the incubating Steelhead in the lower American River.  Actions by Reclamation to keep water temperatures and reduced daytime air temperatures are responsible for this favorable outcome.

Water Forum staff and consultants have estimates that 85% of the 2015 brood of have Steelhead emerged at this point.

Given this positive news and predictions of cooler weather ahead, Reclamation told stakeholders in a special session of the American River Group today that they will continue releasing 500 cfs from Folsom for the foreseeable future and will continue the power bypass until middle of next week.   After that, the chunk of cold water accessible to the bypass will be mostly used up and Reclamation will end it.
