Should have the hazards marked well. Don't always trust your GPS up there, they can be off by ten, fifteen ft sometimes. What we did was to first, locate our position on the map using the gps, plot a hazard-free route to the next spot, then follow the gps - verifying waypoints to the map along the way. good luck, m
Sorry, I meant to say the map should have them marked. Never been there, just to LOTW but likely same general problem: you can lose a lower unit if you not careful. m
Unless the CHS has improved its Eagle Lake map, the best paper map of Eagle is produced by Fishing Hot Spots. As Larry said, there are spots that are not marked.
Navionics' Canada chip and Lakemaster's Ontario chips include Eagle Lake. Lakemaster's chips tend to provide the most detail.
