Canadice Lake is one of the minor Finger Lakes. Canadice Lake has a shoreline 6.5 miles (10 km) long and a maximum depth of 95 feet (29 m). Because the lake is a water source of Rochester, no houses are permitted on its shore and boats are limited in size and engine power. Long ago, Canadice Lake had cottages all along its shore. In 1872, the city of Rochester decided to use Canadice and Hemlock Lakes as a water supply. The first conduit for water was completed in 1876. By 1947, Rochester purchased all of the shoreline property and removed the cottages so that it could preserve the water supply for its growing population. Although it was difficult for the cottage residents to leave their land, this area is now free of the commercialization that is so rampant on the other Finger Lakes. Ninety-foot-deep Canadice Lake is the smallest of the Finger Lakes, but it has the highest elevation, at 1,096 feet, which is one of the reasons it is such a good water supply for the city. Flow from Canadice Outlet Creek is diverted into the northern end of Hemlock Lake. From there the City of Rochester Water Bureau conditions the water for drinking and sends it north via large pipes.
