Irondequoit Bay is a large bay on the southern shore of Lake Ontario located in Monroe County and offers anglers excellent spring, summer, fall and winter fishing. The bay is 80 feet deep and stretches four miles long by a half mile wide. This diverse fishery is extremely unique to Lake Ontario and also serves as the outlet for Irondequoit Creek which gets a good run of salmon, brown trout, and steelhead. Irondequoit Bay and Creek comprise one of the few major coastal bay and tributary systems in the Great Lakes Plain ecological region of New York.
The wetland area at the south end of the bay is one of the largest coastal marshes on western Lake Ontario. Irondequoit Bay supports a diverse and productive warm water fishery, including such species as smallmouth bass, largemouth bass, northern pike, brown bullhead, white perch, white bass, carp, longnose gar, and lake herring. Extensive beds of submergent and emergent wetland vegetation, found in most coves and tributary mouths, are important spawning and nursery areas for many of these species. Irondequoit Bay and Creek also have significant concentrations of steelhead (lake-run rainbow trout), coho salmon, and brown trout. These salmonids migrate through the bay and enter the creek to spawn between late August and December. Steelhead also migrate into Irondequoit Creek between late February and April. During the winter months, Irondequoit Bay is a popular ice fishing area. As a result of the abundant fisheries resources in the area, anglers from all over the country are attracted to Irondequoit Bay.
