Survey readout
James Lake has a reported maximum depth of 62 ft, and covers about 289 acres in Kosciusko County, Indiana. The Indiana DNR survey maps contours down to 60 ft; the depth between 60 ft and 62 ft is interpolated rather than measured. Coverage is sparse: about 65% of this lake lies well away from any surveyed contour, so most of the shape shown there is interpolated between distant measurements rather than mapped. Depths come from the Indiana DNR survey of 2017.
Measured from the Indiana DNR lake bathymetry survey.
Depth below 60 ft is interpolated. The survey's own contours stop at 60 ft, while it reports a maximum of 62 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 2026-09-21James Lake has a partly natural setting, generally sheltered geometry, some nearby classified roads. No special watercraft restriction is identified in the current source.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Good | 17.2 of 30 | 64% natural land cover within 150 m of shore (16% forest, 48% wetland; 23% developed) |
| Geometric wind exposure | Very Good | 13.8 of 25 | mean fetch 1,187 m · 0% of sampled water within 500 m of shelter · generally short fetch |
| Watercraft controls | None identified | 7.5 of 15 | No special watercraft restriction identified in the current DNR source. Motors permitted, subject to general law. |
| Public access | Good | 12.8 of 15 | 1 DNR fishing access site · DNR directs boaters to a ramp on connected water |
| Road isolation | Good | 7.8 of 15 | some nearby classified roads · 4 INDOT-classified segments within 1.2 km, peak 4,655 vehicles/day |
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
- Low — wide enough that wakes disperse over most of the lake
- Aquatic vegetation
- Low — approximately 2% 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
- High — 16% forest and 48% wetland cover within 150 m of shore

Fishing rules for this lake Beta
Size and daily limits for the 25 species found here — 20 open to harvest.
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.

How to identify invasive species in Indiana lakes →
What does non-native mean?
USGS records identify non-native species that have been documented for this lake or its shoreline. Non-native does not necessarily mean invasive, and historical records do not confirm current presence.

James Lake — common questions
How deep is James Lake?
The Indiana DNR reports a maximum depth of 62 ft for James Lake. The survey's own contours reach 60 ft, so the depth below that is interpolated from the reported maximum rather than mapped.
How big is James Lake?
James Lake covers about 289 acres in Kosciusko County, Indiana.
What fish are in James Lake?
Species with survey, catch or recent-stocking evidence include largemouth bass, muskellunge, northern pike, black crappie, bluegill, bowfin. The page lists all 25 species and the evidence behind each.
Is there public access to James Lake?
The Indiana DNR lists James Lake as open to the public by water rather than from a ramp of its own: its access record reads "James Lake (Use Grassy Creek Ramp)". The launch is on connected water, not on James Lake itself.
Is the depth of James Lake measured or estimated?
The survey contours reach 60 ft while the survey reports a maximum of 62 ft, so the basin between those depths is inferred by the model rather than measured.
