The lake

Survey readout

Monocle Lake is mapped to a depth of 55 ft on the Michigan DNR survey and covers about 148 acres in Chippewa County, Michigan.

Measured from the Michigan DNR inland-lake contour survey (depths read from the survey's isobath field; this lake's summary-depth column is blank in the source).

Paddling

Paddling Index methodology v1.0 · calculated 2026-08-21
61 / 100MixedData confidence: Medium

Monocle Lake has a partly natural setting, generally sheltered geometry, limited nearby major-road exposure. No special watercraft restriction is identified in the current source.

Why this score?5 components

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
Moderate — approximately 28% 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
Moderate — 50% forest and 12% 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: MI DNR Watercraft Control Areas (2026-08), USGS/MRLC NLCD Land Cover (2021), MDOT Annual Average Daily Traffic (2025) and MI DNR bathymetric survey outline (0 ft isobath).

Fish you might catch

Fishing rules for this lake Beta

Size and daily limits for the 2 species found here — 2 open to harvest.

These are hook-and-line size, daily limit and season rules. Gear, spearing and bow fishing, spawning closures and rod limits are set by other Fisheries Orders and are not shown here.

Smallmouth BassOpen to harvestMinimum size: 14" · Daily limit: 5 (FO-215 · statewide inland) The 5 is in any combination of Largemouth and Smallmouth Bass, not 5 of each (FO-215.23A).

Beta. This panel is newly published. Every value is parsed from the Michigan DNR fisheries orders and hand-checked against the printed digest, but the coverage and wording are still under review. If anything here disagrees with the Michigan DNR's Fisheries Orders or its printed digest, the DNR is right — the signed Fisheries Order is the legal text; the digest summarises it.

Notable catches

Master Angler program · 1996

One Master Angler catch is on record for this lake: 23.5″ white sucker in 1996 on nightcrawler.

Master Angler entries are fish that met the program’s minimum size and were registered by the angler — they show what this lake has produced, not what a day here will produce. A catch on record is history, not a species listing: “Fish you might catch” lists only species with current evidence. Source: Michigan DNR Master Angler data.

DNR stocking

state stocking record · 1979–1991

Fish the Michigan DNR has planted in this lake — what was added, distinct from what a survey netted above.

Walleye324,624 stocked · 1979–1991 · 9 plantings
Smallmouth bass8,100 stocked · 1982–1983 · 2 plantings

No stockings recorded since 1991 — shown as history.

Quick answers

Monocle Lake — common questions

How deep is Monocle Lake?

The deepest contour on the Michigan DNR bathymetric survey of Monocle Lake is 55 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 Monocle Lake?

Monocle Lake covers about 148 acres in Chippewa County, Michigan.

What is the average depth of Monocle Lake?

The estimated mean depth of Monocle Lake is 21.7 ft, calculated from the survey contours.

What fish are in Monocle Lake?

Species with survey, catch or recent-stocking evidence include smallmouth bass, white sucker. The page shows the evidence behind each.

Is there public access to Monocle Lake?

No public launch for Monocle Lake appears in the Michigan DNR access data. That is not the same as the lake being private -- municipal and private ramps are not in that source.
