All ponds and lakes ultimately become uplands. It is called Succession.
Succession in small Urban lakes, like Indian Lake, is accelerated due to the large amounts silt and nutrients in runoff from fertilized lawns, resident waterfowl. It may take only a couple of decades to become uplands. If the municipality has the funds, dredging and application of aquatic herbicides can delay succession, but it is very costly. Why back when, the State had The Clean Lakes Program which provided funds to municipalities.
Large, deep lakes like Round Valley Res., will take centuries, or more, to become uplands. But ultimately, it will happen.
