Summary
Completed in 2009, this earth dam stands at 34 feet in height and has a storage capacity of 108 acre-feet. The dam serves multiple purposes including fire protection, stock watering, and small fish pond maintenance, while being regulated by the State Engineer's Office.
Situated on the Grapnel Draw river, Feldspar boasts a relatively low hazard potential and fair condition assessment as of October 2019. With a spillway width of 30 feet and a maximum discharge of 231 cubic feet per second, the dam ensures effective water management for the surrounding area. Despite its moderate risk assessment level, the dam is inspected every 5 years to ensure its structural integrity and safety measures are up to standard.
With Liz Cheney (R) representing the area in Congress, Feldspar remains a crucial water resource within the Omaha District. The dam's location along I-90 and its contribution to the local irrigation and water supply systems highlight its significance in sustaining agriculture and wildlife in the region. For water resource and climate enthusiasts, Feldspar serves as a prime example of efficient dam infrastructure supporting various essential functions while adhering to rigorous state regulatory standards.

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.
