Robin Run is a stream in Bucks County, Pennsylvania. It starts in Buckingham Township and flows southeast. The stream joins Mill Creek in Wrightstown Township. Mill Creek then flows into the Delaware River.

Robin Run is a major branch of Mill Creek. It is part of the larger Delaware River system. The stream has a dam, creating Robin Run Lake.

The Bucks County government now manages the dam at Robin Run. This dam is one of six county dams in the area.

In 2009, an incident occurred where many fish were lost from Robin Run Lake. Since then, the lake has not been restocked with fish.

The Path of Robin Run

Robin Run starts near Lower Mountain Road in Buckingham Township. It flows southeast through a small pond. Then, it enters Robin Run Lake. This lake is a reservoir built by Bucks County in 1971.

After the lake, Robin Run continues into Wrightstown Township. It then meets Mill Creek. Robin Run does not have any other large streams flowing into it.

Rocks and Land Around Robin Run

Robin Run begins in an area with a type of rock called the Lockatong Formation. This is a sedimentary rock layer. It formed during the Triassic Period. Sedimentary rocks are made from layers of mud, sand, and tiny bits of rock that build up over time.

The Lockatong Formation includes rocks like argillite, shale, and limestone. These rocks are named after Lockatong Creek in New Jersey.

In 2018, the United States Geological Survey received a grant. They used it to study the dam and the land around Robin Run.

The Lockatong Formation rocks are light to dark gray, greenish-gray, and black. They are very fine-grained sandstone, silty argillite, and layered mudstone. These rocks often formed in ancient lakes or along shorelines.

As Robin Run flows, it quickly enters an area with the Brunswick Formation. This is another sedimentary rock layer. It formed during the Jurassic and Triassic periods. The Brunswick Formation contains shale, mudstone, siltstone, and argillite.
