Like Canadice Lake, Hemlock Lake is used as a water reservoir for the City of Rochester. Therefore, there are no cottages on the shore, and certain activities are either banned (such as swimming) or restricted.
The forests surrounding the southern end of the lake are classified as "old growth" forests. This means that they were not cut down by settlers and naturally re-grown, as in the case of the other lakes.
The Eagle Crest Preserve is a nature conservancy found on the west side of the lake and is dedicated to protecting the old growth forests.
The 415 acres of untouched hemlock, beech, sugar maple, and oak trees provide the ideal setting for hiking, bird watching, and fishing.
Boats are limited to 17 feet in length and a maximum of 10HP engine power, which makes Hemlock Lake an ideal spot for canoeing, kayaking, and fishing.
This is the only Finger Lake not named by Native Americans.
