Chalkers Mill Pond measures 10.3 acres, and is surrounded by forest except for one house at the pond’s southern end. A road runs along the pond’s western side.

The pond was completely covered with white water lily (Nymphaea odorata) during our July 2005 survey. Common bladderwort (Utricularia macrorhiza) also was abundant, occurring in large patches throughout the pond. The floating-leaved watershield (Brasenia schreberi) occurred in scattered, sometimes large patches, especially at the pond's southern end. Spikerush (Eleocharis species) was found in one large patch, which spanned from the west to east shores, in the southern portion of the pond. Slender naiad (Najas flexilis), spineless hornwort (Ceratophyllum echinatum), ribbon-leaf pondweed (Potamogeton epihydrus), small pondweed (Potamogeton pusillus), spotted pondweed (Potamogeton pulcher) and floating-leaf pondweed (Potamogeton natans) occurred throughout the pond in very small to medium-sized patches.
