Water clarity at Lilley Lake
Clear water. Across summers from 2018 to 2023, Lilley Lake averaged 4.55 m (15 ft) of visibility down into the water, so you can typically see several feet down in midsummer.
Nobody has taken a water sample here that we can find. Michigan's environmental agency measures clarity on lakes like this one from satellite images instead, which is why this page reports how clear the water is but carries no A–F grade.
Clear is not the same as clean. A lake can be easy to see through and still carry high nutrient levels, and a naturally tea-stained lake can be perfectly healthy. The A–F grade on other lakes is built from phosphorus and algae measured in a laboratory, and clarity alone cannot stand in for it.
The same satellite images put summer algae here at roughly 2.83 micrograms per litre. Estimating algae from orbit is far less exact than measuring clarity, so that figure is worth knowing and is not part of any rating.
Lilley Lake is a 60-acre lake in Newaygo County, Michigan with a maximum depth of 36 feet (14-foot average).
