Avery Pond is a shallow 35.7-acre waterbody located in Preston, Connecticut. The pond is developed only on the western side with a public boat launch for recreation.

       The CAES IAPP previously surveyed Avery Pond in 2005 and found dense growth of Robbins' pondweed (Potamogeton robbinsii) throughout the whole lake. Our 2014 survey found a reduced abundance of Robbins' pondweed growing only around the shoreline of the lake. We also found two types of lily pads: white water lily (Nymphaea odorata) andyellow water lily (Nuphar variegata), which were both found in 2005, along with several new native species: common duckweed (Lemna minor), pickerelweed (Pontederia cordata), leafy pondweed (Potamogeton foliosus), and humped bladderwort (Utricularia gibba).
