Chase Reservoir, a 71.1 acre lake, that has recently been acquired by the town of Killingly. The lake is surrounded by forest, and access is limited to boats that can be carried in between the trees. Although it is a natural water body, the water level was raised with the construction of a dam at the southern end of the lake.

Chase Reservoir supports abundant plant growth, but no invasive species .  Potamogeton perfoliatus was the most abundant plant found during our August 2005 survey. It was found growing in dense stands in water at least 10 feet (3 m) deep and across the whole lake bottom.  Vallisneria americana grew along the shore, virtually all around the lake, in water up to 6 feet (2 m) deep.  Najas flexilis also was abundant, occurring in large patches throughout the lake.

Both Elatine minima and Sparganium sp. were found along the northwest and northeast shores.  Brasenia schreberi, Nymphaea odorata, Utricularia purpurea, Lemna minor, Spirodela polyrhiza and Wolffia brasiliensis were only found in small patches on the northwest shore of the lake.  Eriocaulon aquaticum, Sagittaria sp., and Nuphar variegata were found on all of the shores except for the south shore, and Nuphar variegata was found in the middle of the lake.  Isoëtes tuckermannii, Eleocharis sp., Gratiola aurea and Juncus paleocarpus were found in a few small patches along the west and east shore.  Polygonum amphibium and Utricularia vulgaris were only found on the north shore and Charaphyte was only found as a large patch in the southern end of the lake.   Glossostigma cleistanthum was restricted to several discrete patches near the shore in the southeastern part of the lake.
