Dennis Pond is a fair perch and pickerel pond. Anglers casting spoons, spinners and submergent plugs, or fishing with live shiners, should find action from ample numbers of pickerel up to 20 inches long. The yellow perch are the most abundant species, and there are good numbers in the 8 to 9 inch size range. There are few large specimens of either species due to the acidity and infertility of the water.
