As a condition of the FERC license (No. 1061) for the Phoenix Project, minimum instream flows for the South Fork Stanislaus River were established to maintain habitat values for aquatic species.
Due to drought conditions, a flow variance monitoring program was developed and implemented to maintain aquatic habitat quality during periods when minimum instream flows could not be attained. Sequoia performed numerous studies for FERC license compliance including fish population assessments using backpack electrofishing units and block nets to isolate and survey selected reaches of the river; visual encounter surveys for foothill yellow-legged frog on the Middle Fork Stanislaus River over 2 years; fish habitat assessment surveys and stranding potential studies; and water quality monitoring using a handheld multi-parameter constant read water quality sampler.
