Assessment is based on results of fish tissue (RAFT) monitoring in 1995.
Basis for Assessment
Due to lack of either recent chemical or biological information, changed the assessment of support of the Class B(WW) aquatic life uses to NAS. Fish consumption uses remain assessed as FS based on results of 1995 RAFT fish tissue monitoring. Previous assessments of the lower Nishnabotna River were developed without the benefit of information on the condition of the biological communities protected by the Class B(WW) water quality standards. Monitoring is needed to determine the status of the aquatic communities and to determine the degree to which the Class B(WW) uses may be impaired.
