Stream habitat was rated poor to fair. The stream substrate is mostly rubble, gravel or other stable habitat but covered with a layer of fine clay sediment. Construction activities near the creek mouth appear to be contributing a significant amount of sediment to the creek. In July, a plume could be seen in the receiving waterbody from a particular construction site. Macrophytes are abundant but generally not over abundant.
Filamentous algae is common on the rocky bottom substrate where exposed to sunlight.
Macroinvertebrate samples indicate poor to fair water quality with fairly significant to very significant organic pollution. A brief survey was conducted in August 1992 in a stretch of creek near Spencer Road. Mud Creek receives a considerable amount of suspended solids during runoff events sampled.
