205-acre reservoir near East Haddam. CT DEEP survey water. The lake tops out around 12 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Moodus Reservoir, Lower runs 205 acres with 2.5 miles of edge. Nearly circular (index 1.2), so the story is the bottom, not the bank.
