Healthy streams, rivers, and lakes provide safe drinking water, recreational opportunities, and important habitat for species ranging from the red-shouldered
hawk to steelhead to crayfish and dragonflies. Maintaining healthy streams, rivers, and lakes can reduce the need for water treatment and water supply
costs and make landscapes more resilient to climate change. To determine the health of a waterway and the flora and fauna that live there, investigators
can use a combination of chemical, biological, and physical assessments. Among the characteristics that may be considered are habitat quality,
aquatic life diversity, water chemistry, stream hydrology (water flow processes), the physical channel form, and sediment transport processes of the stream.
