Basis for Assessment

SUMMARY:  The support of the Class A (primary contact recreation) uses was changed from "fully supported / threatened" to "not assessed.   The support of the Class B(LW) aquatic life uses was changed from "partially supported" to "not assessed."  The fish consumption uses remain "not assessed."  EXPLANATION:  The previous assessments of support of the Class A uses (fully supported / threatened"; see above) and the Class B(LW) aquatic life uses ("partially supported"; see above) were based on information in an application for funding as a Section 319 water quality project.   In order to develop an assessment for this lake, however, additional information is needed on the levels of indicator bacteria in the lake (Class A uses) and on the status of the aquatic communities in the lake (Class B(LW) uses).   Thus, considered both the Class A and Class B(LW) uses as "not assessed" for the 2000 report.   Fish consumption uses remain "not assessed" due to the lack of fish tissue monitoring at this lake.
