Survey readout
Reed Lake is mapped to a depth of 7 ft on the Michigan DNR survey and covers about 20 acres in Livingston 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).

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.
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 2026-09-23Reed Lake has a heavily wooded and largely undeveloped 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 | Excellent | 33.3 of 35 | 90% natural land cover within 150 m of shore (20% forest, 70% wetland; 8% developed) |
| Geometric wind exposure | Excellent | 29.4 of 29 | mean fetch 293 m · 100% 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 | 11.2 of 18 | limited nearby major-road exposure · 9 MDOT-classified segments within 1.2 km, peak 1,595 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
- Moderate — narrow in places — wakes would carry across parts of the lake
- Aquatic vegetation
- High — approximately 78% 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 — 20% forest and 70% wetland cover within 150 m of shore
