   Doaneville Pond is a 68.4 acre waterbody located in Griswold.  It is connected to Glasgo Pond by a waterway under a bridge.  Using the public boat ramp on Glasgo Pond and driving under the bridge is the only public access to the lake.  There is a mobile home community near the bridge and other various houses scattered around the shore. There is also a campground in the north center section of the lake.  Boating is popular on the lake as well as using jet skis and water skiing.

   Vegetation in Doaneville Pond is limited to a narrow band along the shore as the pond quickly slopes to a depth where light to restricts plant growth. The 2011 CAES IAPP survey found 22 species of aquatic plants, including one invasive. The invasive plant was Cabomba carolinana (Fanwort). It was found only at the northern tip of the northwest cove. The northern shoreline was the most species rich area of the lake.  All of the plants could be found growing together along the shoreline.  The small, shallow water plant, Glossostigma cleistanthum, and water lily, Nymphaea odorata, occurred most frequently.  The eastern peninsula was the most species rich area of the lake.  Eleven native plants could be found growing together there.

   In shallow waters Elatine species, Eleocharis species, Eriocaulon aquaticum, Glossostigma cleistanthum, Gratiola aurea, and Isoetes species frequently grew together.  Growing along the shore were Polygonum species, Pontederia cordata, Sagittaria species, and unidentified sedges. There were seven floating leaf species: Brasenia schreberi, Lemna minor, Nuphar variegata, Nymphaea odorata, Nymphoides species, Spirodela polyrhiza, and Wollfia species.  Two pondweeds were found, Potamogeton bicupulatus and Potamogeton natans. Najas flexilis was found only in the northern half of the lake while Vallisneria americana was found only in the southern half of the lake.
