Little Blue Saddle is a privately owned earth dam located in Greene Township, Pennsylvania, along the TR Mill Creek. Constructed in 1977, this dam stands at a height of 15 feet and has a length of 470 feet, with a storage capacity of 4207 acre-feet. With a drainage area of 2.9 square miles, it serves as a vital water resource for the surrounding area.

However, it has a relatively high inspection frequency of twice a year, with the last inspection conducted in March 2021. The dam's primary purpose is listed as "Other," indicating its multifaceted role in water resource management in the region. Overall, Little Blue Saddle serves as a critical infrastructure for water storage and flood control in Beaver County, Pennsylvania, under the jurisdiction of the Pittsburgh District of the US Army Corps of Engineers.
