1,275-acre reservoir near Hanover. The Codorus State Park lake in south-central PA, a well-known muskie and largemouth fishery with 26 miles of shoreline. The lake tops out around 101 ft. The depth chart comes from Pennsylvania Department of Conservation and Natural Resources bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Lake Marburg maps at 1,226 acres behind 26.4 miles of shoreline — 2 islands included. With a shoreline index of 5.4, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 34% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 3.8 mi end to end and 2.8 mi across at its widest. It sits in York County. Its nearest charted neighbour, Prettyboy Reservoir, is 13 mi to the southeast.
Spring muskellunge on Lake Marburg hold shallow, usually 3 to 12 ft. By summer they slide out to 8 to 25 ft, and by winter most fish are in 15 to 35 ft. Prime time lands in the evening and early morning. The summer box starts with a double-10 bucktail or a topwater (walk-the-dog / creeper).

Early season largemouth bass use the shallows, holding in 2 to 10 ft. Summer is an 8 to 20 ft game here, winter a 15 to 35 ft one. Best bite is early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.

Spring crappie on Lake Marburg hold shallow, usually 2 to 8 ft. They move out to 10 to 25 ft in summer and finish the year down in 15 to 35 ft. The feeding windows run early morning and the evening. The summer box starts with a jig trolled/spider-rigged or a small crankbait (trolled).

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
