Summary
Built in 1976, this earth dam stands at a height of 31 feet and has a storage capacity of 3964 acre-feet. The dam serves multiple purposes, including fire protection, stock watering, flood risk reduction, and irrigation, making it a crucial water resource for the region.
Despite its importance, Tract 37 is facing significant challenges. A recent inspection in July 2018 revealed poor condition assessment and a significant hazard potential. With an uncontrolled spillway and a moderate risk rating, this dam requires urgent attention to ensure its safety and functionality. Additionally, the dam lacks an Emergency Action Plan (EAP) and updated emergency contacts, raising concerns about its readiness to handle potential disasters.
With its key role in water management and irrigation in the area, Tract 37 serves as a vital infrastructure for the community. However, its deteriorating condition and lack of proper risk management measures highlight the need for immediate action to safeguard this essential water resource. Climate enthusiasts and water resource professionals must prioritize the rehabilitation and maintenance of Tract 37 to ensure its continued contribution to the region's water supply and environmental sustainability.

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.
