Although most of the watershed is generally closed to the public, the protected area includes forest roads, buildings, three dams and reservoirs, two hydroelectric power stations, and other infrastructure used by government employees who manage the forest and the water supply system.
The system includes a concrete dam and spillway, added to the natural outlet of Bull Run Lake.
The dam, completed in about 1960, was preceded in 1915 by a timber-and-rockfill structure and later by other measures to increase the lake's storage capacity and to prevent seepage.
These measures raised the lake's usable storage from about 2.8 billion US gallons (11,000,000 m³) to about 4.3 billion US gallons (16,000,000 m³), an increase of about 55 percent.
Dam 1, which impounds Reservoir 1, is a concrete arch-gravity dam about 200 feet (61 m) high, and Dam 2, a rockfill structure about 110 feet (34 m) high, impounds Reservoir 2.
 Although the two reservoirs combined can hold up to about 17 billion US gallons (64,000,000 m³), their total usable storage is only about 10 billion US gallons (38,000,000 m³).

The raw water intake (headworks) at Bull Run is just below Dam 2.
This is where water is diverted from the river for chlorination and then routed into three distribution conduits for delivery to Portland.
About 23 percent of the watershed's annual runoff is diverted to the city's water supply.

The main roads within the BRWMU include Forest Road 10, which runs for much of its length along the north side of the river.
It links the community of Bull Run near the mouth of the river and Forest Road 18 (Lolo Pass Road) east of Bull Run Lake.
Branching off Forest Road 10 downstream of Reservoir 2, Forest Roads 12 and 14 form a loop south of the river.
The loop extends as far east as Goodfellow Lakes, near the source of the Little Sandy River.
Below the BRWMU, Bull Run Road, open to the public, crosses the river between the community of Bull Run and Dodge Park.

The Bull Run River Bridge, a 240-foot (73 m) Pennsylvania-petit truss span that carries Bull Run Road, was originally the west truss of the Burnside Bridge over the Willamette River in downtown Portland.
It includes parts made of wrought iron as well as steel, and its truss portals incorporate nautical design elements meant for Portland, an inland seaport.
Built in 1894, the bridge was moved to Bull Run in 1926, when a new Burnside Bridge replaced the old one.
The Sandy River Bridge over the Sandy River at Dodge Park, just upriver from the mouth of the Bull Run River, was the 300-foot (91 m) east truss of the Burnside Bridge.
