Summary
This earth dam stands at a height of 26 feet and has a maximum storage capacity of 125 acre-feet, serving to control the flow of the TR-Little Tabo Creek. With a low hazard potential and a moderate risk assessment rating, this dam plays a crucial role in managing the water resources in the area.
The dam, measuring 475 feet in length and featuring an uncontrolled spillway with a width of 60 feet, helps to maintain normal storage levels of 23 acre-feet. Despite its age, Tabo Creek Watershed Dam E-21 has not been rated for its condition and lacks an emergency action plan. However, its design and construction by the Natural Resources Conservation Service ensure its structural integrity and functionality in mitigating the risk of flooding in the region.
As a vital infrastructure for water resource management in the Tabo Creek Watershed, Dam E-21 represents a collaborative effort between local government and federal agencies. With its strategic location and design, this dam contributes to the overall stability and sustainability of the watershed, highlighting the importance of proactive monitoring and maintenance to ensure its continued effectiveness in the face of changing climate conditions.

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.
