Summary
With a dam height of 32 feet and a length of 580 feet, this earth dam serves multiple purposes including debris control, fire protection, stock or small fish pond, in addition to flood risk reduction. It has a storage capacity of 66 acre-feet and a surface area of 2.9 acres, contributing to the management of water resources in the region.
Located in Nemaha County, Kansas, Dd No A-1 (Murphy) is regulated by the Kansas Dept. of Agriculture, with state jurisdiction, permitting, inspection, and enforcement in place. The dam has a low hazard potential and a moderate risk assessment rating, indicating its importance for mitigating flood risks in the area. The spillway type is uncontrolled with a width of 50 feet, ensuring effective water discharge during high flow events.
Despite not being rated for its condition assessment, Dd No A-1 (Murphy) remains a crucial infrastructure for water resource management in the region, with a primary purpose of flood risk reduction. As climate change continues to impact water availability and extreme weather events, the role of such dams in protecting communities and ecosystems becomes increasingly significant, highlighting the importance of continued monitoring and maintenance for sustainable water management.

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.
