The Huron at Flatrock has two types of muskies. Most are trickle down fish from Belleville and are likely the most common to run into at this time of year. However, the river also gets a spawning push of muskies from Lake Erie. The numbers of spawning fish are limited and some may remain through the year. The last time the river was surveyed down there the only muskies that were captured were fish that were stocked in Belleville.
