Completed in 1977, this dam serves multiple purposes, with a storage capacity of 73,000 acre-feet of water. The dam's primary function is listed as "Other," and it is regulated by the Pennsylvania Department of Environmental Protection, with frequent inspections and enforcement measures in place to ensure its structural integrity and safety.

Despite being classified as having a high hazard potential, Little Blue Run has been assessed to be in fair condition. The dam underwent modifications in 2005 and 2007 to enhance its hydraulic capabilities. The surrounding area has a drainage area of 2.9 square miles and a surface area of 770 acres, making it a significant water resource in Beaver County, Pennsylvania. With a normal storage capacity of 64,754 acre-feet, the dam plays a crucial role in managing water resources in the region.

The dam's location near the Little Blue Run river and its association with the Pittsburgh District of the US Army Corps of Engineers highlight its importance in flood control and water management efforts. The presence of Conor Lamb as the local congressional representative underscores the political significance of this water resource. Climate and water enthusiasts interested in the management and regulation of dams will find Little Blue Run to be a compelling case study in the intersection of environmental protection, infrastructure development, and public safety.
