Lake productivity & trophic state
Satellite estimateSatellite-estimated classification: Mesotrophic. Moderate nutrient levels and biological productivity. Based on satellite estimates of summer chlorophyll-a (LAGOS-US LANDSAT, 2020). No lake-specific measurement is available in this dataset.
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 2026-09-23Sandy Bottom Lake has a mostly natural, lightly developed setting, well sheltered geometry, some nearby classified 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 | Very Good | 24.4 of 35 | 73% natural land cover within 150 m of shore (16% forest, 58% wetland; 23% developed) |
| Geometric wind exposure | Excellent | 27.1 of 29 | mean fetch 530 m · 36% 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 | Good | 7.6 of 18 | some nearby classified roads · 43 MDOT-classified segments within 1.2 km, peak 8,773 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 3% 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 — 16% forest and 58% 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.

How deep is Sandy Bottom Lake?
The deepest contour on the Michigan DNR bathymetric survey of Sandy Bottom Lake is 40 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 Sandy Bottom Lake?
Sandy Bottom Lake covers about 58 acres in Livingston County, Michigan.
What is the average depth of Sandy Bottom Lake?
The estimated mean depth of Sandy Bottom Lake is 26.4 ft, calculated from the survey contours.
What fish are in Sandy Bottom Lake?
Species with survey, catch or recent-stocking evidence include black crappie, redear sunfish. The page shows the evidence behind each.
Is there public access to Sandy Bottom Lake?
No public launch for Sandy Bottom 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.
