Summary
The dam stands at 26 feet tall with a length of 700 feet, providing a storage capacity of 50 acre-feet for the TR-CAVEL CR watershed. The dam serves multiple purposes, including flood control and irrigation, and is regulated by the Oklahoma Water Resources Board.
Despite being classified as having a low hazard potential, Daugherty Gss No.1 is considered to have a very high risk due to its condition not being rated and lacking emergency action plans. The dam features a controlled spillway and one valve outlet gate for water release. The last inspection of the dam took place in 2010, with an inspection frequency of every 5 years. The risk management measures for the dam are currently unspecified, raising concerns for the potential impact of a failure on downstream areas.
Overall, Daugherty Gss No.1 presents an intriguing case study for water resource and climate enthusiasts, as it highlights the importance of regular inspections, maintenance, and emergency preparedness for dams. The dam's location in a high-risk area emphasizes the need for proactive risk assessment and management to ensure the safety of surrounding communities and the sustainability of water resources in the region. Further research and action may be necessary to address the identified risks and improve the resilience of Daugherty Gss No.1 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.
