Specifications include, but are not limited to: Snyderville Basin Water Reclamation District is seeking technical assistance with reviewing and facilitating various aspects of the ECWRF UPDES permit. The scope of work being requested includes general permitting support, technical review, agency coordination support and performing several studies. The proposed studies are organized into the following three phases: 1) Water Quality Modeling, Monitoring, and Assessment; 2) Fisheries and Habitat Evaluation; and 3) Final Assessment and Comprehensive Report. A fourth phase, focused on support of an appropriate administrative path, is envisioned to be agreed upon at the completion of the first three phases of work. The studies will evaluate appropriate modeling tools and inform the development of a calibrated water quality model to assess DO dynamics in East Canyon Creek. The main goals of the studies are to: 1. Assess East Canyon Creek’s attainment of the dynamic, temperature-dependent DO standard calculated using high-frequency temperature data, at an elevation of 6,255 feet, and 90% DO saturation using the most appropriate water quality model. 2. Assess the presence, seasonality, and frequency of ELSs of cold-water, warmwater, and other fish species in the mainstem of East Canyon Creek. 3. Provide updated fishery, water quality, and habitat information on East Canyon Creek to evaluate progress since the completion of the 2010 TMDL and evaluate the attainability of the current use. 4. Assess the impact and success of restoration activities completed in the watershed on the health of East Canyon Creek since the completion of the 2010 TMDL.
