- inventory of sources of pollution in the watershed.
- actual TMDL calculation as described above.
- water quality restoration plan (also called an "implementation plan") to be put into action by local groups in the watershed.
4. The DNR asks Iowans to review the draft water quality improvement plan.
5. The DNR meets again with Iowans to gather their comments on the plan and discuss how locals can use the plan to create a local watershed improvement group and project.
6. Locals use information in the water quality improvement plan to form a local watershed group and apply for grant funding to get the project started.
