Tyler Lake, Goshen - 2005

Land at the northern half of Tyler Lake is free of development and is swampy. Three streams enter the lake through the area. Houses have been built on most of the rest of the lake shore. The state maintains a boat ramp on the western shore. The maximum depth in the lake is 23 feet (7 m), and the mean depth is 13 feet (4 m). Tyler Lake supports a highly diverse community of aquatic plants, including at least three species on the state's list of endangered species. No single species was dominant, but aquatic plants were abundant in shallow water all around the 187-acre lake.

Two shallow coves at the north end of the lake are particularly diverse. Eelgrass (Vallisneria americana) occurred through most of the area, but yellow water lily (Nuphar variegata), white stem pondweed (Potamogeton praelongus), clasping-leaf pondweed (Potamogeton perfoliatus) and flat-stemmed pondweed (Potamogeton zosteriformis) also were abundant. Other species occurring in the area included humped bladderwort (Utricularia gibba), common bladderwort (Utricularia macrorhiza), Canadian waterweed (Elodea canadensis), white water lily (Nymphaea odorata), slender naiad (Najas flexilis), large-leaf pondweed (Potamogeton amplifolius), and water marigold (Megalodonta beckii).

The northern half of the lake's east shore supported large patches of eelgrass, coontail (Ceratophyllum demersum), southern naiad (Najas guadalupensis), clasping-leaf pondweed, white stem pondweed, Robbins' pondweed (Potamogeton robbinsii), as well as smaller patches of large-leaf pondweed and Canadian waterweed. Along the southern half of the shore, slender naiad was most abundant, although eelgrass, clasping-leaf pondweed, variable pondweed (Potamogeton gramineus), and other species also were recorded.

A shallow-water cove in the southwest part of the lake supported abundant white water lily, eelgrass, and coontail in the most shallow water, while deeper water was occupied by Robbins' pondweed, white stem pondweed, clasping-leaf pondweed, and southern naiad. Robbins' pondweed was abundant along the lake's western shore, with scattered patches of flat-stemmed pondweed, white stem pondweed, western waterweed (Elodea nuttallii), eelgrass, water marigold, yellow water lily, white water lily, clasping-leaf pondweed and other species. The center of the lake, where the water was more than 4 m deep, was free of plants.
