Measured from the Michigan DNR inland-lake contour survey.

Additional depth details9 contours

Contour depths: 0–42 ft
Recorded point soundings: 42 ft

49.6% of the surface sits over water shallower than 10 ft; 26.3% 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 Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.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 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

33 / 100ModestData confidence: Medium

Green Oak Lake has a substantially developed setting, generally sheltered geometry, substantial 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	0.7 of 35	18% natural land cover within 150 m of shore (8% forest, 8% wetland; 68% developed)
Geometric wind exposure	Very Good	20.7 of 29	mean fetch 819 m · 0% of sampled water within 500 m of shelter · generally short 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	Modest	2.9 of 18	substantial nearby higher-volume roads · 39 MDOT-classified segments within 1.2 km, peak 4,464 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 10% 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 — 8% forest and 8% 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) and MDOT Annual Average Daily Traffic (2025).

Size and daily limits for the 1 species found here — 1 open to harvest.

These are hook-and-line size, daily limit and season rules. Gear, spearing and bow fishing, spawning closures and rod limits are set by other Fisheries Orders and are not shown here.

PumpkinseedOpen to harvestMinimum size: no size limit · Daily limit: 25 (FO-215 · statewide inland) The 25 is in any combination of the sunfishes — Bluegill, Pumpkinseed, Black and White Crappie, Rock Bass, Green, Longear and Redear Sunfish, Warmouth and hybrids — not 25 of each (FO-215.23A).

Beta. This panel is newly published. Every value is parsed from the Michigan DNR fisheries orders and hand-checked against the printed digest, but the coverage and wording are still under review. If anything here disagrees with the Michigan DNR's Fisheries Orders or its printed digest, the DNR is right — the signed Fisheries Order is the legal text; the digest summarizes it.

Master Angler entries are fish that met the program’s minimum size and were registered by the angler — they show what this lake has produced, not what a day here will produce. A catch on record is history, not a species listing: “Fish you might catch” lists only species with current evidence. Source: Michigan DNR Master Angler data.
