Higby Reservoir #1 is a 61.1 acre reservoir located in Middletown, CT. There are four reservoirs in this area.  A causeway leading into Higby Reservoir #2 is found along the middle of the eastern coast of the reservoir.  Water enters the reservoir from a channel in the northwest corner. 

The 2010 survey revealed the presence of five plants, none of which are invasive.  Sagittaria graminea can be found around the entire lake. The western, southern, and lower eastern coasts have the most dense presence of the plant.  Smaller patches are found in the northeast corner. The next most common plant was Eleocharis acicularis. It was found in small to medium patches around the perimeter of the lake.  Utricularia gibba was the third most common plant and was found in small patches sporadically around the perimeter.  Four patches of Elatine minima were found. It was only present along the eastern coast. The least frequent plant found was Gratiola aurea. One small patch was found in the north east corner.
