Survey readout
Lake Fenton is mapped to a depth of 90 ft on the Michigan DNR survey and covers about 889 acres in Genesee 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).

Other waters with a public launch on this map: Lake Ponemah. Their launches are not marked on the model — only Lake Fenton’s own are.
43.1% of the surface sits over water shallower than 10 ft; 44.8% is deeper than 20 ft; the survey shows 3 distinct basins. Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.

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.Field and satellite readings disagree for this lake: a Secchi disk water-clarity reading of 19 ft was recorded in 2009, while the satellite estimate is 12 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.
- 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 2026-09-23Lake Fenton has a substantially developed setting, moderate open-water exposure, substantial nearby higher-volume roads. Watercraft controls: Slow-no-wake zones.
Why this score?5 components
Included in the index

|---|---|---|---|
| Natural setting | Modest | 0.6 of 30 | 19% natural land cover within 150 m of shore (5% forest, 14% wetland; 72% developed) |
| Geometric wind exposure | Good | 10.6 of 25 | mean fetch 1,616 m · 0% of sampled water within 500 m of shelter · moderate open-water fetch |
| Watercraft controls | Slow-no-wake zones | 10.2 of 15 | Speed limit; Slow — no wake — designated zones only |
| Public access | Good | 12.8 of 15 | 1 site with DNR boating-facility records · 4 ramp lanes · 43 trailer spaces |

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 4% 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 — 5% forest and 14% 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.
