389-acre lake near Williamsport. A shallow, weedy PFBC-owned impoundment north of Williamsport managed under Big Bass regulations, with annually stocked walleye. The lake tops out around 17 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Rose Valley Lake runs 367 acres with 5.1 miles of edge. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 88% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 1.4 mi, about 0.8 mi across. For a second option, Lake Nephawin lies 19 mi northeast.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 5 to 17 ft, wintering in 5 to 17 ft. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
