Summary
Completed in 1980, this earth dam stands at a height of 26 feet and stretches 2000 feet in length. It has a NID storage capacity of 1755 acre-feet and a normal storage capacity of 95.4 acre-feet, serving a drainage area of 5.49 square miles along the PAWNEE RIVER-TR.
Despite its low hazard potential, Dd No 1-17 is regulated and inspected by the Kansas Department of Agriculture, meeting all state regulatory requirements. The dam features an uncontrolled spillway with a width of 75 feet and has no outlet gates. The last inspection was conducted in 2011, with a moderate risk assessment rating of 3. While the condition assessment is not rated, the dam is currently considered to be in a stable condition.
With its strategic location and effective flood risk reduction capabilities, Dd No 1-17 plays a crucial role in protecting the surrounding area from potential flooding events. Its operational efficiency and compliance with state regulations ensure the safety and security of the community it serves, making it a valuable asset in water resource management and climate resilience efforts in Pawnee, Kansas.

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.
