SCCWRP along with Larry Walker Associates is working with the City of Los Angeles (CLA), Bureau of Sanitation and Environment (LASAN), and the City of Burbank to develop and implement a temperature study to better understand and characterize the relationship between effluent temperature and temperature impacts to the WARM beneficial use in the LA River downstream of the Donald C. Tillman, LA/Glendale and Burbank Water Reclamation Plants. To do this, the project team is evaluating aquatic life uses in the LA River to then characterize the relationship between water temperature and the ability to support warm water aquatic life. Specifically, the project team, in consultation with a Technical Advisory Committee (TAC), identified the following study objectives:
• Objective 1—Determine the wholly or partially aquatic-dependent taxa that are present, were historically present, or could be present given the current habitat conditions in the Los Angeles River.
• Objective 2—For each taxon identified in Objective 1, describe the relationship between waterbody temperatures and the probability (or likelihood) that different aquatic life stages are supported.
• Objective 3—Determine how the relationships between waterbody temperature and the support of aquatic life vary based on the taxon’s location in the river and seasonality.
• Objective 4—Determine the critical exposure times, durations, and/or frequencies associated with the temperature relationships described in Objectives 1 through 3.
• Objective 5—Evaluate how other physical factors (e.g., shading, groundwater discharge, availability of substrate, flow, etc.) and climate change could potentially influence temperature effects on biological communities.
• Objective 6—Analyze relationships between effluent discharge temperature and in-river temperature, including how river temperature changes as a function of distance from the discharge location and downstream physical characteristics.
