West Lake, Guilford - 2005
West Lake is a 52-acre lake located in Guilford, CT. Our August 2005 survey found nineteen species of aquatic plants. Only minor naiad (Najas minor) was invasive. It was the most abundant plant found in the lake, found in moderate quantities throughout the entire southern half as well as sizable patches around the edges in the north. A native species of the same genus, southern naiad (Najas guadalupensis) was also common, occurring with large-leaf pondweed (Potamogeton amplifolius) in patches around most of the edge. Robbins' pondweed (Potamogeton robbinsii) and coontail (Ceratophyllum demersum) are two other common submersed plants found in sizable patches. Two floating-leafed plants, white water lily (Nymphaea odorata) and yellow water lily (Nuphar variegata) were also common along the edges, with much smaller quantities of watershield (Brasenia schreberi).
