Description: Streams with EPA 303d biennial water quality reports. Streams, river segments, and lakes on this list do not meet their designated use/s based on water characteristics (e.g. dissolved oxygen, pH, fecal coliform bacteria, metals, organic pollutants, etc).

Description: Streams with EPA 305b biennial water quality reports. These reports identify the designated use/s for each stream, river segment, or lake and whether the water characteristics (e.g. dissolved oxygen, pH, fecal coliform bacteria, metals, organic pollutants, etc) are capable of supporting that use. Those not meeting the requirements are put on the 303d list.
