Scope and Applicability This manual has been developed by the Kentucky Division of Water (KDOW) as guidance for any biologist or environmental professional involved in the uniform and accurate collection, field processing, field handling, and quality assurance/quality control (QA/QC) of habitat and macroinvertebrate data for TMDL alternative studies and watershed-based plans. The methods defined herein must be followed in order for the data to be used in water quality assessments by KDOW. Any data submitted to KDOW for review will undergo QA/QC and those identified as not following the methods set forth in this document will be flagged and reviewed for data usability. 2. Definitions Aufwuchs – The plants and animals adhering to parts of rooted aquatic plants and other open surfaces.
