  Bioassessment Program Back BWQP Home Page   

Stonefly Since 2000, the Bioassessment Program has conducted annual surveys that focus on the ecological integrity of Nevada’s wadeable rivers and streams by monitoring the biological, chemical, and physical habitat. The biological habitat includes collection of benthic macroinvertebrates and periphyton for community composition, and noting the extent and quality of riparian habitat. Chemical indicators include in-situ measurements and independent laboratory analysis of various water quality chemical parameters. Physical habitat includes bank stability and stream channel characterizations such as substrate, depth, and flow. All three parameters are integral in the assessment of the overall ecological integrity of Nevada’s wadeable rivers and streams. Sites include probabilistic and random, reference condition, impaired targeted and repeat sites.

The Nevada Quality Assurance Program Plan (QAPrP) for the Bioassessment Program establishes specific quality requirements for the collection and management of the bioassessment data.
