Subject

Assessment of salt impairments and development of salt mass balance in the Lower Salinas River and Reclamation Canal watersheds.

Description

A November 2015 report prepared by Tetra Tech for California Central Coast Regional Water Quality Control Board and the U.S. Environmental Protection Agency, Region IX. The purpose was for the informed development of salt-related TMDLs by the CCRWQCB and a salt and nutrient management plan for the Salinas Valley aquifers. Three reaches reported 2010 303(d) listings for salt-related impairments in these watersheds including impairments due to chloride, sodium, electrical conductivity, and total dissolved solids – Lower Salinas River, Santa Rita Creek, and Alisal Creek. This report provides data analysis and a literature review (Sections 1 through 5), development of a water and salt mass balance tool (Sections 6 through 8), and salt source assessment (Section 9). The results of the analysis would provide a strong foundation for assessing salt sources and understanding salt mass balance in the study area, but can be improved with refined representation of cropland locations, rotations, and irrigation practices.
