Summary
4044sr, serves multiple purposes including fire protection, stock watering, and small fish pond management. Built in 1960, this earth dam stands at a height of 24 feet with a hydraulic height of 21 feet and a structural height of 28 feet. It has a storage capacity of 39 acre-feet, providing essential water resources for the surrounding area.
With a surface area of 3.18 acres and a drainage area of 0.12 square miles, the T55nr76w31sese dam controls the flow of the N. Hall Draw river or stream. Despite being classified as low hazard potential, the dam's condition is assessed as fair, with the last inspection conducted in August 2018. The spillway is uncontrolled with a width of 10 feet, facilitating a maximum discharge of 212 cubic feet per second to manage excess water effectively.
For water resource and climate enthusiasts, the T55nr76w31sese dam presents a fascinating case study in sustainable water management and infrastructure development. Its multi-purpose functionality, coupled with regulatory oversight and regular inspections, highlights the importance of maintaining and monitoring critical water infrastructure to ensure the safety and well-being of local communities and ecosystems.

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.
