It is approximately 4.1 miles (6.6 km) long and flows through Scott Township, Blakely, and Dickson City.

Channelization work was done on the creek in 1975 by the Pennsylvania Department of Environmental Resources, which has had the effect of reducing flooding.

Its relatively narrow watershed occupies parts of Scott Township, Blakely, Archbald, and Dickson City.

Macroinvertebrate taxa such as mayflies (Ephemeroptera), stoneflies (Plecoptera), and caddis flies (Trichoptera) inhabit the creek as well.

Several tenths of a mile further downstream, the creek turns south-southeast, flowing through a water gap alongside Pennsylvania Route 347 and entering Blakely.

After several tenths of a mile, the creek crosses a highway and flows south-southwest in a much smaller valley.

[5] Additionally, runoff from Pennsylvania Route 347 and residential properties impacts the water quality of the creek in Blakely.

[1] At its mouth, the peak annual discharge of Hull Creek has a 10 percent chance of reaching 580 cubic feet per second.

[6] At the border between Scott Township and Blakely, the peak annual discharge of Hull Creek as a 1 percent chance of reaching 780 cubic feet per second.

[6] A mid-20th-century report estimated the volume of surface seepage into mine workings at Hull Creek was 9.53 gallons per minute per inch of rainfall.

The rate of streambed seepage in the area was estimated to be 17.02 gallons per minute per inch of rainfall.

[2] One of the more prominent waterfalls in the watershed of the Lackawanna River, the Blakely Falls, are on Hull Creek.

[4] The Blakely Falls are a "picturesque" post-glacial gorge cut through sandstone of the lower Llewellyn Formation.

For 0.3 miles (0.48 km) after the waterfall, the creek has a high gradient, with rock ledges, plunge pools, and slides.

[4] Channelization work was done on 1 mile (1.6 km) of Hull Creek in Blakely by the Pennsylvania Department of Environmental Resources in 1975.

[4] A mid-20th-century report found that 0.901 square miles (2.33 km2) of the watershed of Hull Creek was on coal measures.

[7] The banks of the creek contain glacial drift, with culm pile debris and eroded material.

[3] The part of the watershed that is upstream of the border between Blakely and Scott Township has an area of 2.26 square miles (5.9 km2).

However, large floods in Scott Township have still caused local inundation of structures along the creek.

[4] The rehabilitation of a bridge carrying State Route 1029 over the creek in Scott Township was once planned.

[14] In southern Scott Township, Hull Creek is flanked by native trees and understory.

[4] At three sites on Hull Creek, the EPT (Ephemeroptera, Plecoptera, and Trichoptera) Taxa Richness ranged from 4.00 to 16.00 in a 2013 study.

The former is a method of determining community composition by considering both taxonomic richness and evenness of individuals.
