Summit Lake Creek begins in a valley in Newton Township. It flows east-northeast for several tenths of a mile, passing through the Interlaken Lake, entering South Abington Township, and crossing Pennsylvania Route 307 before turning southeast and crossing Interstate 476.

Summit Lake Creek has no named tributaries. However, it has an unnamed tributary, which is known as "Unt 28530".

A reach of Summit Lake Creek is considered to be impaired by sedimentation/siltation and temperature. The probable sources of the impairment are infrastructure and upstream impoundments. This reach is 1.66 miles (2.67 km) long. Another reach of the creek is considered to be impaired by water/flow variability. This reach is 1.30 miles (2.09 km) long. The probable source of the impairment is urban runoff/storm sewers. The unnamed tributary Unt 28530 is also impaired.

The elevation near the mouth of Summit Lake Creek is 1,063 feet (324 m) above sea level. The elevation near the source of the creek is between 1,260 and 1,280 feet (380 and 390 m) above sea level.

A concrete slab bridge carrying State Route 4032 over Summit Lake Creek was built in South Abington Township in 1904. It is 21.0 feet (6.4 m) long. A concrete tee beam bridge carrying US Route 11 over the creek was constructed in 1936. This bridge is 36.1 feet (11.0 m) long and is also situated in South Abington Township.

The Maple Lake Dam was constructed on Summit Lake Creek in the 1800s. However, it was removed in December 2006. In 2011, Pennsylvania American Water, awarded a $2500 grant to the Clarks Summit Shade Tree Commission to reforest the area at the mouth of the creek and to clean up its streambed to avert potential flash flooding problems.

The entire drainage basin of Summit Lake Creek is a Trout-Stocked Fishery and a Migratory Fishery.
