PHASE I REPORT NORTH FORK – LOWER CROW RIVER TMDL

The purpose of this project is to develop a TMDL for the impaired waters listings for the North Fork –
Lower Crow River. The project is broken down into three phases:
· Phase I – Data review and recommendations
· Phase II – Monitoring and data analysis
· Phase III – TMDL Development
These phases are illustrated in Figure 1a.

This report addresses Phase I of the study and is outlined further in Figure 1b. It is important to note that
Figure 1b illustrates the original intent of the work elements, however, due to data limitations some of the
elements will require further development once additional data is collected. For example, only limited
relationships have been identified for the causes of impairment at this time. This report addresses the
elements in the Phase I outline.
