Upper Chesapeake Bay has a one-two bass punch that is a spring knockout. Striped bass flood onto the Susquehanna Flats in early April, and in early May, fishing for tidal black bass heats up. The striper fishery is the marquee attraction. “It’s a fantastic opportunity to catch lots of 16- to 24-inch stripers on flies and light tackle,” says Martin Gary of the Maryland Department of Natural Resources. “Forty-pounders aren’t unusual, and 100-fish days can be routine.” Sweet Spots: For stripers, fish channel edges nd on top in 2 to 6 feet of water during overcast days What’s Hot: Chug Bugs Local Advice: “It’s very easy to run aground. You want to have a good chart, follow the channels, and watch what other boats are doing,” says Joe Bruce of Fishermen’s Edge in Catonsville. rime Time: March through May More Info: Fish Hawk Guide Service, 410-557-8801; Capt.
