The Subbasin Survey Program consists of two-year assessments in each of the six subbasins on a rotating schedule.
Year-1 surveys consist of point-in-time water chemistry, macroinvertebrate, and habitat data collection and assessments of approximately 100 stream sites on the major tributaries and areas of interest in the selected subbasin.
Year-2 surveys focus on a particular region or small watershed within the subbasin, and typically consist of more intensive, repeated sampling at a smaller number of locations. The Year-2 sampling is tailored for the individual needs of a chosen watershed or region or is designed to complement and support another already ongoing SRBC project.
