Habitat Analysis

The quality of physical habitat of all sampling sites used for the KCP assessment was estimated using EPA=s visual-based habitat assessment protocols (Barbour et al. 1999; http://www.epa.gov/owow/monitoring/rbp) at the time collections of biota were made. Each of 10 habitat parameters is given a score from 0 to 20 based on defined characteristics for the parameter. A score of 0 is given for the lowest quality and a score of 20 is given for the highest quality. The scores for each parameter are then summed, and a maximum score of 200 is indicative of highest quality habitat. The assessments at each site were performed by two or three individuals, and the assessors= parameter scores were averaged to get a final score.

The lowest total score (48) was obtained for Blue River site BLK 32.1 which is the channelized stream segment adjacent to the KCP. Other sites which received poor overall assessment scores were BLK 33.9 and the most upstream site on Indian Creek (INK 21.9). These three sites were characterized as channelized with low bank stability and insufficient riparian vegetation

The highest scores were obtained at Indian Creek site INK 18.5, which was adjacent to a small neighborhood park, and at Coffee Creek (CFK 3.3). These sites had good substrate diversity, a wide range of flow types, no obvious evidence of channelization, relatively stable banks, and fairly well developed riparian zones on both sides of the stream.
