The lake

Survey readout

Bluegrass Lake has a reported maximum depth of 68 ft, and covers about 204 acres in Warrick County, Indiana. The Indiana DNR survey maps contours down to 65 ft; the depth between 65 ft and 68 ft is interpolated rather than measured. Depths come from the Indiana DNR survey of 2011.

Measured from the Indiana DNR lake bathymetry survey.

Depth below 65 ft is interpolated. The survey's own contours stop at 65 ft, while it reports a maximum of 68 ft. The basin between those two depths is inferred by the model, not measured — so the shape of the deep hole is an estimate, and the deep-spot marker shows the deepest depth actually surveyed.

Paddling

Paddling Index methodology v1.0 · calculated 2026-09-21
58 / 100MixedData confidence: High

Bluegrass Lake has a mixed natural and developed setting, generally sheltered geometry, nearby higher-volume roads. Watercraft controls: Electric motors only.

Additional paddling considerations

These describe the lake but are not part of the v1 Paddling Index and do not change the number above.

Wake sensitivity
Moderate — narrow in places — wakes would carry across parts of the lake
Aquatic vegetation
Low — approximately 3% mapped coverage · NAIP aerial imagery (NDVI)
Observed motorized activity
Unknown — No lake-level measurement of boat traffic is available. Legal permission to operate motors is not evidence of use.
Wildlife habitat potential
Limited — 15% forest and 8% wetland cover within 150 m of shore
How this index is calculated. The Paddling Index is a relative composite derived from lake geometry and public environmental, access, roadway and watercraft-control data. It is not a user review, a safety rating, or a prediction of an individual outing. Differences of a few points should not be treated as meaningful — an 84 and an 82 are broadly comparable. Components and weights: natural setting 30%, geometric wind exposure 25%, watercraft controls 15%, public access 15%, road isolation 15%; observed motorboat activity is weighted 0% because no defensible lake-level measurement exists. Where a component has no data the remaining weights are renormalized and the confidence rating is lowered; below Medium confidence no number is shown.

Fishing rules for this lake Beta

Size and daily limits for the 4 species found here — 3 open to harvest, 1 with a special rule or closed season.

These are hook-and-line size and daily limit rules. The fishing code sets no closed season for these species on inland lakes, but posted property rules can close a water — see the notes. Gear, spearing and bow fishing, netting and bait collection are set by other sections of 312 IAC 9 and are not shown here.

Largemouth BassSpecial rulesLargemouth bass here: 2 per day, at least 18 inches (312 IAC 9-7-6(i)) — not the statewide 5 at 14 inches.
Black CrappieOpen to harvestMinimum size: no size limit · Daily limit: 25 (312 IAC 9-7-14(a)) Black and white crappie together.
Beta. This panel is newly published. Every value is transcribed from the Indiana Administrative Code (312 IAC 9-7) and checked against the Indiana DNR's 2026-27 Fishing Regulations Guide, but the coverage and wording are still under review. If anything here disagrees with 312 IAC 9-7 or the Indiana DNR's guide, the DNR is right — the Administrative Code is the legal text; the guide summarizes it.
No closed season in the fishing code: 312 IAC 9-7 sets no season for these species on inland lakes (trout and salmon “at any time of year”, 9-7-13(d)(1)). Posted property rules can still close a water or bar entry (312 IAC 8-2-1) and 312 IAC 9-6-6 closes a few named areas, so check the property before you go. The possession limit is twice the daily bag limit (312 IAC 9-1-12.1); fish already processed and stored at your primary residence do not count toward it (312 IAC 9-2-8(d)).
Black CrappieOpen to harvestMinimum size: no size limit · Daily limit: 25 (312 IAC 9-7-14(a)) Black and white crappie together.
Largemouth BassSpecial rulesLargemouth bass here: 2 per day, at least 18 inches (312 IAC 9-7-6(i)) — not the statewide 5 at 14 inches.

Official rule text for this lake
“An individual must not take or possess more than two (2) largemouth bass per day, and an individual must not take or possess a largemouth bass unless the largemouth bass is at least eighteen (18) inches long from the following designated waters: (5) Bluegrass Pit at Blue Grass Fish and Wildlife Area in Warrick County.” — 312 IAC 9-7-6(i), Indiana Administrative Code

Quick answers

Bluegrass Lake — common questions

How deep is Bluegrass Lake?

The Indiana DNR reports a maximum depth of 68 ft for Bluegrass Lake. The survey's own contours reach 65 ft, so the depth below that is interpolated from the reported maximum rather than mapped.

How big is Bluegrass Lake?

Bluegrass Lake covers about 204 acres in Warrick County, Indiana.

What fish are in Bluegrass Lake?

Species with survey, catch or recent-stocking evidence include largemouth bass, muskellunge, black crappie, white crappie. The page shows the evidence behind each.

Is there public access to Bluegrass Lake?

Yes. The Indiana DNR lists 2 public access sites on Bluegrass Lake: Blue Grass FWA Blue Grass Pit (boat ramp); Blue Grass FWA Blue Grass Pit (boat ramp).

Is the depth of Bluegrass Lake measured or estimated?

The survey contours reach 65 ft while the survey reports a maximum of 68 ft, so the basin between those depths is inferred by the model rather than measured.
