Stream C Monitoring at Flambeau Mine Site - NOR 4_11

Purpose

Recent monitoring at the Flambeau mine site near Ladysmith (Rusk Co.) has shown that acutely toxic concentrations of copper and zinc are regularly present in the runoff entering Stream C. Stream C is an intermittent tributary of the Flambeau River. Monitoring is proposed to assess the impacts of this toxicity to Stream C and the Flambeau River near the mouth of Stream C. The monitoring would also further identify the source areas of the metals found. Water samples from 10 sites on 3 dates (5 dates for 2 of the sites) would be collected and tested for metals and other parameters (see lab budget). A broad range of metals would be tested on 2 dates and a more limited range of metals would be tested on the other dates. Sediment samples from 8 sites would be tested for metals and other parameters (see lab budget). Macroinvertebrate samples would be collected from 5 sites (2 per site). Fish surveys would be done at 2 sites on 2 dates.

Objective

The site needs to be evaluated for 303d inclusion since water quality standards for copper and zinc are being exceeded.

Outcome

Performance Measures: These are milestones that will be reported on in the Division Quarterly Report. Please estimate dates in a manner that encourages success. 1) Number of sample sites associated with the project. 19 2) Number of sampling events associated with project. 9 3) Estimated date when sample collection will be complete. June 30, 2011 4) Estimated date when all data will be entered into appropriate database. Dec. 31, 2011 5) Estimated date when final report will be complete. April 30, 2012
