The department needs current fish, habitat, and macroinvertebrate data for streams in the watershed to augment the county land and water plan and to determine priorities for work in the future. The data will be used to determine whether these streams are achieving their attainable use in order to update the watershed tables, list water that are not meeting their attainable use, and assess the overall health of the watersheds as required by Section 303(d) of the Clean Water Act.
