48 / 100ModestData confidence: High

Nyona Lake has a substantially developed setting, generally sheltered geometry, some nearby classified roads. 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: 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: Limited — 17% forest and 9% 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), IN DNR Fishing Access Sites (2026-08) and INDOT Annual Average Daily Traffic (2021). Conditions change quickly — check current weather and local conditions before going out.

Fishing rules for this lake Beta

Size and daily limits for the 17 species found here — 13 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.

Brown BullheadOpen to harvestMinimum size: no size limit · Daily limit: no limit (312 IAC 9-7-14(d) · “Bullhead”)

Gizzard ShadOpen to harvestMinimum size: no size limit · Daily limit: no limit (312 IAC 9-7-14(d) · “Gizzard shad”) No limit on harvest, but live shad may not be kept: live gizzard or threadfin shad may be possessed or used as bait only on eight named waters (Brookville, Cecil M. Harden, Monroe and Patoka reservoirs, Lakes Freeman and Shafer, Hardy Lake, the Ohio River main stem excluding its embayments), and only where collected. Everywhere else shad must be killed immediately (312 IAC 9-6-8(b)–(d)).

Golden ShinerOpen to harvestMinimum size: no size limit · Daily limit: none stated (312 IAC 9-7-15) A minnow under the code’s definition (312 IAC 9-6-1). Minnows may be taken at any time of year by minnow trap, dip net, seine, cast net or lawful sport-fishing methods; the section states no bag or size limit, caps transport out of Indiana at 100 minnows in any 24-hour period (licensed bait dealers, scientific-purposes licensees and those commercially raising minnows in private waters for sale excepted), and requires a bait dealer’s license to sell (312 IAC 9-7-15).

Hybrid SunfishRule not confidently resolvedNot named in 312 IAC 9-7 or in the DNR guide's limits table. Please check with the Indiana DNR (317-232-4200) before keeping this species.

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.

Yellow PerchOpen to harvestMinimum size: no size limit · Daily limit: no limit (IN DNR 2026-27 guide, statewide table · 312 IAC 9-7-18 (Lake Michigan only)) The code limits yellow perch only on Lake Michigan (15); the DNR's statewide table prints inland perch as unlimited.

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.
