Gs Dd No C-133 is a flood control structure located in HOLTON, Kansas, along the BANNER CREEK-TR river. Designed by KING ENGINEERING, this dam serves the primary purpose of flood risk reduction, with additional functions including debris control. With a dam height of 28.5 feet and a length of 450 feet, the structure provides a maximum storage capacity of 83.6 acre-feet and a normal storage of 19.6 acre-feet. Despite its low hazard potential and moderate risk assessment, the dam has not been inspected since May 2003 and is currently rated as "Not Rated" in terms of condition assessment.

The Gs Dd No C-133 dam, part of the Kansas City District, has a spillway width of 65 feet and a maximum discharge capacity of 780 cubic feet per second. While the dam itself is classified as an earth dam with a buttress core type, it lacks outlet gates and is considered uncontrolled in terms of spillway type. The structure is not regulated by the state, with no state jurisdiction, permitting, inspection, or enforcement in place. The risk management measures for the dam remain unspecified, and it has not been assigned a Dam Safety Action Classification (DSAC) as of yet.

Overall, Gs Dd No C-133 represents a vital component in the flood risk reduction efforts in Jackson County, Kansas. As a locally owned structure with no federal agency involvement, its importance lies in protecting the surrounding community from potential inundation events. However, with limited recent inspections and condition assessments, there is a need for increased monitoring and maintenance to ensure the continued safety and functionality of this critical water resource infrastructure.
