Survey readout

Troy-Cedar Lake has a reported maximum depth of 84 ft, and covers about 97 acres in Whitley County, Indiana. The Indiana DNR survey maps contours down to 80 ft; the depth between 80 ft and 84 ft is interpolated rather than measured. Depths come from the Indiana DNR survey of 2019.

Measured from the Indiana DNR lake bathymetry survey.

Depth below 80 ft is interpolated. The survey's own contours stop at 80 ft, while it reports a maximum of 84 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

61 / 100MixedData confidence: Medium

Troy-Cedar Lake has a mixed natural and developed setting, generally sheltered geometry, little nearby major-road exposure. 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	Mixed	11.7 of 35	38% natural land cover within 150 m of shore (6% forest, 32% wetland; 15% developed)
Geometric wind exposure	Very Good	23.0 of 29	mean fetch 679 m · 0% of sampled water within 500 m of shelter · generally short fetch
Watercraft controls	None identified	8.8 of 18	No special watercraft restriction identified in the current DNR source. Motors permitted, subject to general law.
Public access	Not listed	—	No DNR-listed access site. Township, county and road-end launches are not in this source, so this is not evidence that access is poor — the component is excluded and the remaining weights are renormalized.
Road isolation	Excellent	17.6 of 18	relatively isolated from major roads · 1 INDOT-classified segment within 1.2 km, peak 450 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 10% 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 — 6% forest and 32% 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 13 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.

BluegillOpen to harvestMinimum size: no size limit · Daily limit: no limit (312 IAC 9-7-14(d) · “Bluegill”)

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)).

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)).

BluegillOpen to harvestMinimum size: no size limit · Daily limit: no limit (312 IAC 9-7-14(d) · “Bluegill”)

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

Channel CatfishOpen to harvestMinimum size: no size limit · Daily limit: 10 (312 IAC 9-7-3(b), (d)) The 10 is catfish in aggregate of any size from a lake or reservoir. Of those, not more than one channel catfish 28 inches or longer, one blue catfish 35 inches or longer and one flathead catfish 35 inches or longer per day.

Common CarpOpen to harvestMinimum size: no size limit · Daily limit: no limit (312 IAC 9-7-14(d) · “Carp”)

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)).

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.

Spotted GarOpen to harvestMinimum size: no size limit · Daily limit: no limit (312 IAC 9-7-14(d) · “Gar”)

SuckerOpen 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.

White BassOpen to harvestMinimum size: no size limit · Daily limit: 12 (312 IAC 9-7-7) 12 in any combination of white bass and hybrid striped bass, of which not more than two may exceed 17 inches.

White SuckerOpen 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.

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

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.

Quick answers

Troy-Cedar Lake — common questions

How deep is Troy-Cedar Lake?

The Indiana DNR reports a maximum depth of 84 ft for Troy-Cedar Lake. The survey's own contours reach 80 ft, so the depth below that is interpolated from the reported maximum rather than mapped.

How big is Troy-Cedar Lake?

Troy-Cedar Lake covers about 97 acres in Whitley County, Indiana.

What fish are in Troy-Cedar Lake?

Species with survey, catch or recent-stocking evidence include channel catfish, largemouth bass, bluegill, bowfin, brown bullhead, white bass. The page lists all 13 species and the evidence behind each.

Is there public access to Troy-Cedar Lake?

No public launch for Troy-Cedar 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.

Is the depth of Troy-Cedar Lake measured or estimated?

The survey contours reach 80 ft while the survey reports a maximum of 84 ft, so the basin between those depths is inferred by the model rather than measured.
