The primary function of the Biomonitoring and Aquatic Studies Section (BASS) is to conduct environmental monitoring of aquatic resources, with an emphasis on the assessment of biological integrity. The section’s activities include: the collection, processing and analysis of biological samples; the assessment of physical habitat features; the collection of chemical water quality samples; the assessment of monitoring data results to ensure that data are of the highest possible quality and that the assessment results are appropriately integrated into a wide variety of DEC management programs. BASS conducts more than 100 comprehensive biological assessments annually, with emphasis on evaluation of fish and aquatic macroinvertebrate communities in running waters. BASS provides information and technical assistance to many DEC permit, regulatory, and management programs. BASS also conducts special studies in areas of special concern such as acid rain, malformed frogs, aquatic nuisance control and seasonal pools. Current staff (6 individuals) have combined experience in their positions in excess of 125 years.
