Survey readout

Doyle Lake is mapped to a depth of 10 ft on the Michigan DNR survey and covers about 16 acres in Washtenaw 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).

59.4% of the surface sits over water shallower than 10 ft. Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.

Lake productivity & trophic state

Satellite estimate

Satellite-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 2026-09-23

86 / 100Very GoodData confidence: High

Doyle Lake has a heavily wooded and largely undeveloped setting, well sheltered geometry, some nearby classified roads. No special watercraft restriction is identified in the current source.

Component	Rating	Points of weight	Measurement
Natural setting	Excellent	30.0 of 30	98% natural land cover within 150 m of shore (29% forest, 69% wetland; 2% developed)
Geometric wind exposure	Excellent	25.0 of 25	mean fetch 332 m · 100% of sampled water within 500 m of shelter · short fetch in most directions

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: Moderate — approximately 16% 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 — 29% forest and 69% 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 bathymetric survey outline (0 ft isobath), USGS/MRLC NLCD Land Cover (2021), MI DNR Watercraft Control Areas (2026-08), MI DNR Boating Access Sites (2026-08) and MDOT Annual Average Daily Traffic (2025). Conditions change quickly — check current weather and local conditions before going out.
