DNR Seeking Info on Lake Vermilion Research Buoy

A DNR buoy near Spider Island in Vermilion’s Big Bay has recently escaped its mooring. The buoy and its attached temperature sensors were deployed in May to continuously record water column temperatures in the 70-foot deep hole near Spider, the deepest spot on Lake Vermilion.

If you notice the buoy floating free on the east end of Vermilion or washed up on shore, please contact DNR Large Lake Biologist Matt Hennen, 218-300-7810, matthew.hennen@state.mn.us.
