Survey readout
Gulliver Lake is mapped to a depth of 25 ft on the Michigan DNR survey and covers about 830 acres in Schoolcraft 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).

45% of the surface sits over water shallower than 10 ft; 19.9% is deeper than 20 ft. Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.

Lake productivity & trophic state
Satellite estimateSatellite-estimated classification: Eutrophic. Higher nutrient levels and biological productivity, often with more algae or aquatic plant growth. Based on satellite estimates of summer chlorophyll-a (LAGOS-US LANDSAT, 2020). No lake-specific measurement is available in this dataset.Field and satellite readings disagree for this lake: a Secchi disk water-clarity reading of 8.9 ft was recorded in 2004, while the satellite estimate is 6.2 ft. Treat the satellite-estimated classification with caution.
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.
- Mesotrophic2–7 µg/L · moderate nutrient levels and biological productivity.
- Eutrophic · this lake7–30 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 2026-09-23Gulliver Lake has a substantially developed setting, moderate open-water exposure, nearby higher-volume roads. 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 | Modest | 4.8 of 35 | 34% natural land cover within 150 m of shore (4% forest, 30% wetland; 40% developed) |
| Geometric wind exposure | Good | 9.9 of 29 | mean fetch 1,998 m · 0% of sampled water within 500 m of shelter · moderate open-water 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 | Mixed | 4.8 of 18 | nearby higher-volume roads · 21 MDOT-classified segments within 1.2 km, peak 6,386 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 0% 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 — 4% forest and 30% wetland cover within 150 m of shore

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.

“A large area of Gulliver Lake consists of shallow, sandy shoal areas. Cover along the shoreline is generally sparse with scattered weed beds; downed trees and other woody debris are also sparse. The bottom substrate consists of mainly sand in the shallow areas along the shoreline. Gravel, cobble and rock are dispersed along the northern shoreline.”
