Summary
Constructed in 1999 by the USDA NRCS, this dam serves multiple purposes and stands at a height of 33 feet with a hydraulic height of 32 feet. With a normal storage capacity of 31 acre-feet and a drainage area covering 1448 acres, Keith Arnold provides essential flood control and water resource management for the surrounding area.
Despite its low hazard potential and moderate risk assessment, Keith Arnold has not been rated for its condition assessment. The dam features an uncontrolled spillway with a width of 20 feet and a stone core foundation. Its maximum discharge capacity reaches 57 cubic feet per second, with a total length of 379 feet and a storage capacity of 49 acre-feet. While it has not undergone recent inspections or maintenance, Keith Arnold remains a crucial component of water resource infrastructure in the region.
Managed by the Natural Resources Conservation Service, Keith Arnold does not fall under state jurisdiction or regulation. Its location in the Kansas City District and its association with the USDA NRCS highlight its importance in water resource management. As a key structure along the Florida Creek, Keith Arnold plays a vital role in mitigating flood risks and ensuring the sustainable use of water resources in the area.

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.
