Objectives Monitoring is designed to answer the following questions: (1) What is the spatial variability of ambient water quality in the Central Valley? (2) What is the seasonal variability of ambient water quality in the Central Valley? (3) Is there evidence beneficial uses are not being protected? The sites that comprise this project are intended to serve as a long-term framework for a Central Valley trend monitoring program.
