SCCWRP is working with Santa Clarita Valley Sanitation District of the Los Angeles County (District) to implement a temperature study in the Santa Clara River (SCR) to better understand the temperature range protective of the WARM beneficial use and evaluate the presence and thermal tolerance levels of aquatic-dependent taxa. Based on the results of these studies, the District will develop temperature management options that will bring the two WRPs into compliance with the temperature limitation.
The Santa Clara River Waterbody Temperature Study will evaluate temperature threshold protective of the WARM beneficial use considering natural variability and ecological protections. The Study’s objectives are as follows:
• 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.
• 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 SCR and seasonality.
• Objective 4—Determine the critical exposure times, durations, and/or frequencies associated with the temperature relationships described in Objectives 2 and 3.
• Objective 5—Determine how other physical factors in the SCR (e.g., shading, availability of substrate, evapotranspiration, flow, groundwater upwelling) can mediate temperatures and potential effects on biological communities.
