Big Indian Creek 13-C is a vital earth dam located in Gage, Nebraska, designed by the USDA NRCS to serve as a flood risk reduction measure along the TR-Sicily Creek. Completed in 1969, this dam stands at a height of 29 feet with a hydraulic height of 27 feet, providing a storage capacity of 1002 acre-feet to mitigate potential flooding in the area. The dam's structural integrity is regularly inspected by the NE DNR, with the last assessment in May 2016 confirming its satisfactory condition and low hazard potential.

With a normal storage capacity of 122 acre-feet and a drainage area of 2.9 square miles, Big Indian Creek 13-C plays a crucial role in managing water resources in the region. Its stone core and soil foundation contribute to its stability, while the dam's length of 981 feet and volume of 25 acres make it an essential asset for flood control. The dam's location in the Omaha District underscores its significance in safeguarding the surrounding environment and communities from potential water-related disasters.
