279-acre lake near Clarkstown. The lake tops out around 35 ft. The depth chart comes from New York State Department of Environmental Conservation bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
Rockland Lake maps at 279 acres behind 2.7 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. About 57% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.9 mi end to end and 0.7 mi across at its widest. Rockland County claims this one. Hudson River - Tappan Zee to Haverstraw Bay sits 1 mi north — the closest neighbouring chart.
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
| 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 (16 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (16 ft) | Blade bait, Jigging spoon |
When the water first warms, white perch slide up into 4 to 15 ft. Summer is an 11 to 35 ft game here, winter an 11 to 35 ft one. Start at Deep basin. It's a deep basin holding about 35 ft of water and rates prime come summer. The feeding windows run early morning. Keep a small spinner rig drifted or a 1/8 oz jigging spoon rigged through the warm months.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Shallow bay flat (2 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 11 to 35 ft chart-limited; documented 15 to 40 ft | dawn | Deep basin (35 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 11 to 35 ft chart-limited; documented 15 to 45 ft | midday | Deep basin (35 ft) | Jigging spoon (small), Blade bait |
| Winter | 11 to 35 ft chart-limited; documented 20 to 50 ft | dusk | Deep basin (35 ft) | Small rattle spoon, Tungsten + spikes |
Spring muskellunge on Rockland Lake hold shallow, usually 3 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 15 to 35 ft. Put Break off the point first on the milk run — a drop-off near 16 ft that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a double-10 bucktail or a topwater (walk-the-dog / creeper).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (2 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 8 to 25 ft | dusk & dawn | Break off the point (16 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (16 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 15 to 35 ft | midday | Deep basin (35 ft) | Large rubber, crawled slow |
Rockland Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 35 ft down.

Shallow bay flat is the top-rated area: a weed flat in about 2 ft of water that rates prime for largemouth bass in spring. The interactive chart above rates every spot for each species and season.
