Canandaigua Lake State Marine Park

Sucker Brook is a short stream that drains into the northwest corner of Canandaigua Lake, New York, United States. It flows in a 6-mile (9.7 km) hairpin-shaped course from uplands in the town of Canandaigua to the lake, in the eponymous city. The name comes from the white sucker fish abundant in its waters. It may have originally drained into another body of water prior to the formation of the lake, which changed its outlet through stream piracy. Lime dissolved in its waters from the limestone bedrock it flows over creates rare oncolites known locally as "water biscuits' on the north shore of Squaw Island, one of two islands in the 11 Finger Lakes, near its mouth. The brook has seen some pollution issues in recent years, as the channel at its mouth has been widened to increase recreational opportunities available in the area.

Skenoh Island is located at the north end of Canandaigua Lake, near the city of Canandaigua, New York, United States. It is one of two islands in the 11 Finger Lakes. Frequently it is described as New York's smallest state park; however, while it is one of the state's smallest protected areas, it is not formally designated as a state park, but rather it is a "unique area" managed by the New York State Department of Environmental Conservation. The island was previously known as Squaw Island until October 2021, when the name was changed to remove the ethnic slur squaw.It formed from the alluvial deposits of nearby Sucker Brook. Limestone from the brook's bedrock dissolved in its waters forms rare lime carbonate oncolites, known locally as "water biscuits", on its shores. Rises in the lake level following the damming of Canandaigua Outlet have reduced the island to a small portion of its former land. The state and local activists have worked together to shore it up against erosion and prevent it from disappearing.
