An Integrated Assessment of Torch Lake Area of Concern Noel R. Urban, Carol A. MacLennan, Judith A. Perlinger Michigan Technological University Funding provided by Michigan Sea Grant This is Contribution No. 53 of the Great Lakes Research Center at Michigan Technological University Calumet & Hecla operations in Lake Linden ca 1940.

Acknowledgments The authors thank Michigan Sea Grant for funding to enable this integrated assessment. Without the support, insights, historical knowledge and perspectives offered by Sharon Baker, MDEQ site coordinator for many years, this project would not have been possible. We also owe tremendous thanks to the two students, Ankita Mandelia and Emma Schwaiger-Zawisza, whose thesis research contributed major parts of this report. Other people who have contributed to our understanding of the site and its history are too numerous to mention individually, but include state and federal agency personnel, colleagues at MTU and the Keweenaw National Historic Park, TLPAC members, and community members. Administration and staff members at Sea Grant were very helpful in administering the grant, creating and maintaining a web site for the project (http://www.miseagrant.umich.edu/torchlake/), and facilitating compilation of the final report. The assessment was greatly improved thanks to the contributions of eight anonymous reviewers representing agency, scientist, and local citizen viewpoints. Ruins of Quincy powerhouse.
