2,400-acre reservoir near Towson. The lake tops out around 75 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What the data behind the map says about each species, season by season:
On the chart, Loch Raven Reservoir draws 2,197 acres inside 43.2 miles of shoreline, with 3 islands in the mix. That shoreline is heavily fingered (development index 6.6) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 31% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 6 mi with a 3.5-mi widest point. The water lies in Baltimore County. Closest neighbour on DepthScout: Gunpowder Falls, 8 mi northwest of here.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 15 to 35 ft. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 2 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (14 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Back-bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (14 ft) | Blade bait, Jigging spoon |
In spring, crappie run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 10 to 25 ft, and winter fish settle into 15 to 35 ft. Old creek channel is the standout, a creek channel at roughly 20 ft, rated prime for fall crappie. Time it for early morning and the evening. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Old creek channel (20 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Old creek channel (20 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Old creek channel (20 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Early season striped bass use the shallows, holding in 5 to 20 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 20 to 50 ft. Put Creek inflow first on the milk run — an inflow / creek mouth near 9 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a flutter spoon (deep) or an umbrella rig (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Creek inflow (9 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 25 to 60 ft | dawn & dusk | Secondary point (24 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (21 ft) | Topwater walker, Jerkbait |
| Winter | 20 to 50 ft | midday | Old creek channel (20 ft) | Alabama rig (slow), Flutter spoon |
