At the northeast corner of the lake is a canal that meanders through the Parkhurst development and is navigable by boat.

There is a sand bar that connects Nelson Island to the mainland that varies from about three feet to only inches deep, and is sometimes fully exposed in the mid to late summer.

Because of the lake's shallow depth (on average around nine feet), many large rocks pose serious threats.

Acre Rock lies approximately at the town line separating Lakeville and Freetown.

For a boater inexperienced navigating Long Pond, it is always advisable to remain on the western side of the islands when traveling north or south to avoid the many rocks and sandbars that exist.

When entering the lake's southwestern area, to the west of Hemlock Point, avoid the middle of the entrance due to several rocks that are not always marked.
