Here is another map with the GPS numbers for the various reefs! Please note the shallow spot on the map for Crib Reef! There is another shallow spot on Niagara that you should be aware of and is clearly visible on the map! You can damage your boat on either spot with the shallow water conditions so use caution!
Danger Zone 2 is marked with a line of cans that run west to east and are numbered 1 thru 14 and start just South of L-can on the west side of the firing range. That line of cans also cuts across Flat Rock Reef! Zones 1 and 2 are closed to boaters if there will be .50 caliber fire from Camp Perry. That can line has been moved a little further to the North the last couple of years for whatever reason they have. A-can, B-can and C-can marks the outer most northern perimeter line of the firing range and was used when they fired a lot of anti-aircraft flak shells at drones in years past.

I have also reposted the other map so you can see where the patrol boat is usually stationed when Danger Zone 1 is closed to boaters due to small arms fire. It is located just outside and East of the mouth of the Toussaint River and it will be anchored somewhere between Buoy 40 and Buoy 45 marking the perimeter of danger zone 1 and will be flying a large red flag.
