Additional depth details1 contour

Contour depths: 0–5 ft
Recorded point soundings: 5 ft

100% of the surface sits over water shallower than 10 ft; the survey shows 2 distinct basins. Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.

Lake productivity & trophic state

Measured 2019

Classification: Mesotrophic. Moderate nutrient levels and biological productivity. Based on measurements recorded in 2019 (chlorophyll-a 2.9 µg/L).

Trophic state describes how biologically productive a lake is, based on indicators such as nutrients, algae and water clarity. It is not a swimming-safety or overall water-quality rating.

What do the categories mean?

Oligotrophic≤ 2 µg/L · lower nutrient and algae levels, often clearer water and lower biological productivity.
Mesotrophic · this lake2–7 µg/L · moderate nutrient levels and biological productivity.
Eutrophic7–30 µg/L · higher nutrient levels and biological productivity, often with more algae or aquatic plant growth.
Hypereutrophic> 30 µg/L · very high nutrient levels and biological productivity, with a greater potential for heavy algae growth and low water clarity.

Bands are summer (June–August) mean chlorophyll-a, the green pigment in algae, at the EPA 2012 National Lakes Assessment thresholds. Trophic condition can change over time and by measurement method.

Paddling

Paddling Index methodology v1.0 · calculated 2026-09-23

78 / 100GoodData confidence: Medium

Spectacle Lake has a mostly natural, lightly developed setting, well sheltered geometry, limited 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	Very Good	27.1 of 35	78% natural land cover within 150 m of shore (28% forest, 50% wetland; 12% developed)
Geometric wind exposure	Excellent	28.6 of 29	mean fetch 494 m · 59% of sampled water within 500 m of shelter · short fetch in most directions
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	Very Good	13.5 of 18	limited nearby major-road exposure · 12 MDOT-classified segments within 1.2 km, peak 641 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: Moderate — approximately 18% 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 — 28% forest and 50% wetland cover within 150 m of shore

Compare Michigan lakes by Paddling Index →

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 bathymetric survey outline (0 ft isobath), USGS/MRLC NLCD Land Cover (2021), MI DNR Watercraft Control Areas (2026-08) and MDOT Annual Average Daily Traffic (2025). Conditions change quickly — check current weather and local conditions before going out.

Quick answers

Spectacle Lake — common questions

How deep is Spectacle Lake?

The deepest contour on the Michigan DNR bathymetric survey of Spectacle Lake is 5 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 Spectacle Lake?

Spectacle Lake covers about 89 acres in Chippewa County, Michigan.

What is the average depth of Spectacle Lake?

The estimated mean depth of Spectacle Lake is 3.7 ft, calculated from the survey contours.

Is there public access to Spectacle Lake?

No public launch for Spectacle 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.

Do tribal rules apply on Spectacle Lake?

Spectacle Lake has 62% of its shoreline in the Bay Mills Reservation. Fishing, boating and access on reservation and trust-land waters can be governed by the tribe's own regulations as well as the state's, and they can differ for tribal members and non-members. Check with the Bay Mills Indian Community before fishing or launching.
