Grand Lake St Marys Popular Fish - Largemouth Bass

Largemouth Bass Fishing

This year, largemouth bass are growing large in Grand Lake St Marys due to excellent fisheries management and plenty of cover for both baitfish and bass. Fishing for largemouth bass is good virtually any time they are shallow - in spring, mornings in summer, and during warm Fall afternoons. Use shallow crankbaits around rip rap. Around grass use worms, jigs, topwater and spinnerbaits. In deeper water, big worms, jigs and spoons are three good weapons. In winter, spend your time on deeper structure. Smallmouth bass and spotted bass also reside here in good numbers.

Grand Lake St Marys Popular Fish - Crappie

Crappie Fishing

Both black crappie and white crappie reside in Grand Lake St Marys, and crappie are a very popular species this year. The lake has plenty of brush piles where the crappie like to hang out. Crappie fishing is on the rise and they can be found in sizeable schools. Crappie always like cover and structure, so locate brush and vegetation. Using a fish finder can help locate schools of crappie, which tend to stack vertically around cover. In spring and fall focus on the 8 to 12 foot range. As the crappie move deep in summer and winter, follow points out deep, as well as find ledges near channels in deeper water. White crappie, in smaller numbers, also make this lake their home. When the lake freezes over, ice fishing is often a great way to catch a quick limit of crappie.

Grand Lake St Marys Popular Fish - Channel Catfish

Channel Catfish Fishing

This year a healthy population of channel cats populate the waters of Grand Lake St Marys, and can be found all around the lake. In Spring channel cats migrate toward incoming water, so stay up river, away from the main lake. Night fishing for channel catfish often delivers better results than fishing during the day. In early summer look for rocky banks, the bigger the rocks the better. In summer and winter deeper structure is where to look. Fishing for channel catfish is often productive around any kind of structure in the area. Road beds, creek channels and rocky points are all good places to begin. Use a slip sinker or Carolina rig with popular catfish baits. Other catfish in the lake include flathead catfish.
