GLSC Deepwater Science Program delivers annual reports, presentations to Great Lakes fishery managers at annual Lake Committee Meetings


Delivering Information to Fishery Managers in the Great Lakes Basin.

Scientists working within the GLSC Deepwater Science Program delivered their annual reports and presentations at the Great Lakes Fishery Commission’s (GLFC) annual Lake Committee Meetings in Ypsilanti, Michigan, March 25-29, 2019. The Lake Committee Meetings are a forum for state, tribal, and provincial fishery management agencies on each Great Lake to assess the state of fish communities, discuss pressing issues, and plan future management activities. This is the primary annual venue in which USGS Deepwater Science is delivered to the fishery managers. Decisions made by the Lake Committees will form the guiding framework for fishery management across the basin. The annual USGS Lake Reports can be found on the GLFC website. The Lake Committee Meetings agenda includes the following USGS presentations.
