303(d) Listing Evaluation, Data Compilation, and Analyses of the St. Louis River AOC (2843800), Lake Superior (2751220), and its Tributaries.

Purpose

The St. Louis River and adjacent portions of Lake Superior are federally designated as an Area of Concern. This federal desgination places waterbodies within Areas of Concern on the 303(d) list of impaired waters. This project involves evaluating current data and data gaps in 303(d) listed waters and to identify new additions to the 303(d) list in the Lake Superior Basin.

Objective

The WDNR is actively developing and pursuing the Area of Concern delisting targets. Achieving these targets will remove the St. Louis River and portions of Lake Superior from the Area of Concern designation. This could also effectively remove individual waterbodies within the AOC from the 303(d) list. In this process we have realized their is an abundant amount of existing and historical data that is relevant to our management needs. However, this data is spread out among many entities and if many various formats. These agencies and/or partners include: USGS, EPA, MPCA, USFWS, MDNR, universities, tribes, and citizen groups. The specific objective would be to facilitate data exchange and compilation, conduct data analyses, and evaluate water bodies for possible impairment and inclusion on the 303d list. This step is an efficient approach to meeting EPA reporting requirements for Measure SP 12.

Outcome

Performance Measures: 1) Identify all data sources for Lake Superior Basin, including the St. Louis River AOC by one month into project. 2) Meet with contacts to plan data exchange/coordination. 3) Start organizing data in a database compatible format. Investigate possible inclusion into SWIMS database. 4) In process, develop metadata. 5) Conduct data analyses; produce summary.
