Meta Identifier	CDFGwalkerefish
Type of Data	Electrofishing survey
Originator	California Department of Fish and Game
Description	Multi-pass sampling with a backpack electrofisher and block-nets was used at six 30-m sections in October 1981. The method used followed Price and Geary, 1979. Fish were identified, counted, weighed by volumetric displacement, and measured for fork length of salmonids and a sample non-game species. Water quality measurements were also taken before areas were surveyed for fish. After electrofishing, stream widths and depths were measured. In addition, cover, streamflow, streambed composition, pool-riffle-run ratio, and canopy were estimated. See report for details.

Purpose	To determine salmonid populations produced as a result of enhancement flows released from Soulajule Reservoir in the upper drainage. John Emig published Admin. Rpt 84-02 to describe his sampling of 6 sites in watershed.
Data Quality Information	Since selection of sites for electrofishing was non-random, extrapolation for basin population may be biased.
