Located in Rulo, Nebraska, Gs Dd No 3-31 is a local government-owned earth dam completed in 1995 with the primary purpose of flood risk reduction. Designed by Mr. Wilbur Naylor, P.E., this structure stands at a height of 32.4 feet and has a length of 550 feet, providing a normal storage capacity of 34 acre-feet and a maximum storage of 115 acre-feet. With a surface area of 4.8 acres and a drainage area of 0.41 square miles, the dam plays a crucial role in managing water flow in the region.

Managed by the Kansas Department of Agriculture, this dam is state-regulated with permitting, inspection, and enforcement mechanisms in place to ensure its structural integrity and compliance with safety standards. Despite being classified as having a low hazard potential, the dam poses a moderate risk due to its condition assessment being rated as "Not Rated." With a maximum discharge capacity of 744 cubic feet per second and an uncontrolled spillway width of 40 feet, Gs Dd No 3-31 is equipped to handle potential flood events and debris control efficiently.

With a risk management plan in place, it is essential for water resource and climate enthusiasts to monitor the maintenance and performance of Gs Dd No 3-31 to mitigate any potential risks and ensure the continued protection of the surrounding areas from flooding and water-related hazards.
