Summary
Built in 1988 by designers Speaker & King, this earth dam stands at a height of 29 feet and spans a length of 620 feet. The dam serves the primary purpose of flood risk reduction, with additional functions including debris control. With a storage capacity of 260.8 acre-feet and a drainage area of 0.58 square miles, the dam plays a crucial role in managing water flow in the region.
Managed by the Kansas Department of Agriculture, Gs Dd No 4-4a has a low hazard potential and is rated as moderate risk (3). The dam features an uncontrolled spillway with a width of 55 feet and has no outlet gates. While the dam's condition is currently not rated, it undergoes regular state inspection, permitting, and enforcement to ensure its structural integrity and functionality. As a vital infrastructure for flood risk reduction in the area, Gs Dd No 4-4a (Beam) contributes to the overall water resource management efforts in Jackson County.
Water resource and climate enthusiasts will find Gs Dd No 4-4a (Beam) to be a fascinating example of local government-led flood risk reduction infrastructure. Situated in a picturesque location in Muscotah, this earth dam serves as a critical component in managing water flow along the Muddy Creek-TR. With its moderate risk rating and low hazard potential, the dam undergoes regular state oversight to ensure its effectiveness in preventing flooding and protecting the surrounding area. As a key player in water resource management in Kansas, Gs Dd No 4-4a (Beam) exemplifies the importance of sustainable infrastructure development in mitigating climate-related risks.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
