Summary
Built in 1990 by designers Speaker & King, this structure serves the primary purpose of flood risk reduction and debris control. With a height of 26 feet and a length of 615 feet, the dam provides a storage capacity of 100.1 acre-feet and covers a drainage area of 0.21 square miles.
Despite its low hazard potential and moderate risk assessment, Gs Dd No D-73 has not been rated for its condition assessment. The dam features an uncontrolled spillway type with a width of 72 feet and does not have any outlet gates. The structure has not been inspected recently, and its emergency action plan status remains unknown. The surrounding area is represented by Congressman Steven C. Watkins, Jr. (R), with no federal agency involvement in funding, construction, or operation.
Water resource and climate enthusiasts will find Gs Dd No D-73 to be an interesting case study in local government-owned flood risk reduction infrastructure. With its unique design by Speaker & King and location in the Rock Island District of Kansas, this earth dam plays a crucial role in protecting the Valley Falls community from potential flooding events. As further assessments and updates are needed, the dam's condition and risk management measures remain key areas of focus for ensuring its continued effectiveness in mitigating flood 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.
