DNR Resumes Dredging in Grand Traverse Harbor, Houghton County
Dredging operations are set to continue in Grand Traverse Harbor, Houghton County, to address sediment accumulation. This initiative aims to enhance harbor functionality and support local ecosystems while a long-term solution for stamp sand contamination is developed.

The Michigan Department of Environment, Great Lakes, and Energy is resuming dredging in Grand Traverse Harbor this week. This project will remove clean sand that has built up naturally, aiming to maintain harbor operations for recreational and commercial activities.
The dredging addresses stamp sand concerns, which are copper mine tailings from the past century affecting the nearby Buffalo Reef, critical for whitefish and trout spawning. The ongoing efforts highlight the need for a sustainable solution to mitigate the impact of these materials on local habitats.
