Blacktail Dam's main boat ramp is located in the primary campground on the southern shore and provides access to the 172-acre lake, though it is in poor condition and situated centrally within the campground, creating traffic through camping areas.

The ramp lacks dedicated trailer parking and can become congested during peak use periods, particularly around the Fourth of July when the popular destination gets very busy.

Anglers should note that all watercraft must travel counter-clockwise on the lake, and a fish cleaning station and multiple fishing piers are available on-site.
