Prior-to-release.--Obtain ETR samples on about February <br /> <br />~ <br /> <br />26, March 11, 25, and April 8 (last sample to be <br /> <br />obtained just prior to release) at all seven sites. <br /> <br />b. During rise in river stage resulting from release from <br /> <br />reservoir obtain about 6 ETR samples at the five siteS <br /> <br />dm.mstream from the reservoir. These '.Jill have to be <br /> <br />obtaiued very rapidly because of the sharp release from <br /> <br />the reservoir.
