158-acre lake in Warrick County, Indiana. The lake tops out around 68 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. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 142 acres, worked by 5 miles of shoreline. The 3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Roughly 56% of the water is 15 ft or less, the band where the food chain lives. Call it 1.5 mi long by 0.5 mi wide at the broadest reach. It sits in Warrick County. Its nearest charted neighbour, Loon Lake, is 1 mi to the south.
Spring largemouth bass on Bluegrass Lake hold shallow, usually 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 15 to 35 ft. Put Back-bay flat first on the milk run — a weed flat near 5 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Back-bay flat (5 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (11 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (14 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (16 ft) | Blade bait, Jigging spoon |
Early season crappie use the shallows, holding in 2 to 8 ft. Summer is a 10 to 25 ft game here, winter a 15 to 35 ft one. The chart's best answer is Back-bay flat — weed flat, 5 ft, prime for spring. Best bite is early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (5 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Shallow bay flat (11 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow bay flat (11 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Break off the point (16 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Early season bluegill use the shallows, holding in 1 to 6 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 10 to 25 ft. Put Back-bay flat first on the milk run — a weed flat near 5 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a small sponge spider (fly) or a micro tube jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Back-bay flat (5 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (11 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (11 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Shallow bay flat (11 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring channel catfish on Bluegrass Lake hold shallow, usually 3 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 20 to 40 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 after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (11 ft) | |
| Summer | 8 to 25 ft | night & dusk | Break off the point (16 ft) | |
| Fall | 10 to 30 ft | dusk | Break off the point (16 ft) | |

Anglers target largemouth bass, crappie, bluegill, channel catfish on Bluegrass Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species listed for the nearest surveyed lakes in the region, filtered to this lake's depth and habitat.
Back-bay flat is the top-rated area: a weed flat in about 5 ft of water that rates prime for largemouth bass in spring. Every other rated spot, per species and season, is on the map above.
For largemouth bass, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
