Colonial Beach, Mile 36.5S, Potomac River, is a summer resort just north of Mattox Creek. The largest of the piers on the river side of the town is the municipal 450-foot T-head pier 1.2 miles above the south end. The pier has reported depths of 6 feet at the outer end.
Monroe Creek, back of Colonial Beach, is entered between Gum Bar Point, at the south end of the town, and Sebastian Point, 150 yards westward. The creek is used extensively as an anchorage. The dredged channel, marked by lights, buoys, and daybeacons, leads from the entrance of the creek to a basin at Robins Grove Point at Colonial Beach. In 2009, the controlling depths were 6.8 feet in the entrance channel to the basin, thence 5.8 feet in the basin. The entrance is narrow and mariners are requested to transit at low speed to avoid wash damage to vessels moored in the creek.
