Summary

The Steelhead (Oncorhynchus mykiss) is a rainbow trout, born in fresh water streams and spends most of its life in the sea and returns to the streams to spawn more than once in its life span. Center for Ecosystem Management and Restoration, CEMAR has led a steelhead restoration program along the California coast since 2001 through compilation of a digital archive of key information sources, documentation of the historical distribution and current status of salmonid populations, and evaluation of the potential for watersheds to support restored salmonid populations [1].


The steelhead is a rainbow trout that migrates to sea as a juvenile and returns to fresh water as an adult to spawn. Unlike the Pacific salmon, the steelhead trout does not always die following spawning and may spawn more than once and return to the sea after each spawning

Location

The Salinas River consists of more than 75 stream miles and drains a watershed of about 4,780 square miles in Monterey County, California. The river flows northwest from headwaters on the north side of Garcia Mountain to its mouth near the town of Marina [2]. A map of the Salinas Watershed, provided by CEMAR, depicts all of the essential streams in the watershed, streams that are available and suitable for O. mykiss habitat. [3]
