Yellow Dog Sentinels, Marquette County
Sulfide Mining Baseline Water Monitoring: Michigan's Upper Peninsula
Yellow Dog Plains, Marquette County: The Central Upper Peninsula Group’s Yellow Dog Water Sentinels project, ably led by David Allen and John Rebers with a large contingent of volunteers, has conducted 5 years of monthly (non-winter) monitoring on 14 river sites in northern Marquette County. See 2009 dates below. The CUP Group is monitoring the Salmon Trout River, the Yellow Dog River, Cedar Creek, and many small branches and tributaries. The group issued their first report in summer 2007, and submitted their own comments on Kennecott's permit applications, and submitted their water quality information to the DEQ and Department of Natural Resources, using the information to testify at the mine permit hearing. The Sierra Club referenced the CUP Group’s water quality data in the Michigan Chapter's permit comments – and corroborated it with data from the (USGS gauge located on the East Branch Salmon Trout River that indicated very cold water, and extremely low conductivity, in turn indicating extremely clean water. In addition, fairly consistent cold water temperatures indicate almost 100% groundwater inflow, meaning the stream ecosystem is very vulnerable to any changes in groundwater quality. Check back soon for a copy of the 2007 water quality report. Contact Rita Chapman or Dave Allen for more information about this monitoring project.
