Paddling

Paddling Index methodology v1.0 · calculated 2026-10-08
57 / 100MixedData confidence: Medium

Summit Lake has a substantially developed setting, well sheltered geometry, limited nearby major-road exposure. No special watercraft restriction is identified in the current source.

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
High — narrow throughout — passing wakes would reach most of the water
Aquatic vegetation
High — approximately 50% 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 — 8% forest and 16% 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. Sources: USGS NHD waterbody outline, USGS/MRLC NLCD Land Cover (2021), IN DNR Fishing Access Sites (motor restrictions) (2026-08) and INDOT Annual Average Daily Traffic (2021).

Fishing rules for this lake Beta

Size and daily limits for the 10 species found here — 8 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.

Black CrappieOpen to harvestMinimum size: no size limit · Daily limit: 25 (312 IAC 9-7-14(a)) Black and white crappie together.
BluegillOpen to harvestMinimum size: no size limit · Daily limit: no limit (312 IAC 9-7-14(d) · “Bluegill”)
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.

BowfinOpen to harvestMinimum size: no size limit · Daily limit: no limit (312 IAC 9-7-14(d) · “Bowfin”) Roe must stay intact inside the fish while on or beside the water and until processing begins; once removed, roe may not be screened, washed, processed, preserved, stored, kept, given away, sold or transported without a roe harvester's license (312 IAC 9-7-14(f), (g)).
Lake ChubsuckerOpen to harvestMinimum size: no size limit · Daily limit: no limit (312 IAC 9-7-14(d) · “Sucker”) Greater redhorse is endangered in Indiana (312 IAC 9-6-9) and may not be taken — identify redhorse carefully.
Largemouth BassOpen to harvestMinimum size: 14" · Daily limit: 5 (312 IAC 9-7-6(a), (c)(3)) The 5 is black bass in aggregate — any combination of largemouth, smallmouth and spotted bass — not 5 of each.

Quick answers

Summit Lake — common questions

How deep is Summit Lake?

The deepest contour on the Indiana DNR bathymetric survey of Summit Lake is 31 ft. That is the deepest depth the historical survey map records, which may differ from the deepest point of the lake itself.

How big is Summit Lake?

Summit Lake covers about 6.2 acres in Noble County, Indiana.

What fish are in Summit Lake?

Species with survey, catch or recent-stocking evidence include largemouth bass, black crappie, bluegill, bowfin, pumpkinseed, redear sunfish. The page lists all 10 species and the evidence behind each.

Is there public access to Summit Lake?

No public launch for Summit Lake is shown in the Indiana DNR's public access data. That is not the same as the lake being private -- municipal and private ramps are not in that source.
