Iowa Code § 466B.5: Regional watershed assessment, planning, and prioritization.

1. The department of natural resources shall create a regional watershed assessment program. The program shall assess all the regional watersheds in the state.

b. Each regional watershed assessment shall provide a summary of the overall condition of the watershed. The information provided in the summary may include land use patterns, soil types, slopes, management practices, stream conditions, and both point and nonpoint source impairments.

c. In conducting a regional watershed assessment, the department of natural resources may provide opportunities for local data collection and input into the assessment process.

2. In conducting the regional watershed assessment program, the department of natural resources shall provide hydrological and geological information sufficient for the water resources coordinating council to prioritize watersheds statewide and for the various communities in those watersheds to plan remedial efforts in their local communities and subwatersheds.

3. Upon completion of the statewide assessment, and upon updating the assessments, the department of natural resources shall report the results of the assessment to the council and the general assembly, and shall make the report publicly available.
