Summary
Originally constructed in 1970 by the USDA NRCS, this dam stands at a height of 41 feet and has a storage capacity of 261 acre-feet. Situated along the TR-Washita River, it serves as a vital infrastructure for managing water resources in the region.
Despite its low hazard potential, the dam at SCS-Cowden Laterals Site-011 is classified as having a very high risk due to its critical role in flood control along the river. With a controlled spillway and a single valve outlet gate, this structure has not been inspected since 1980, highlighting the need for regular maintenance and monitoring to ensure its continued effectiveness. The dam's risk management measures and emergency preparedness plans are currently not rated or updated, raising concerns about its resilience in the face of potential climate-related challenges.
As a key component of the flood risk reduction system in the area, SCS-Cowden Laterals Site-011 represents a critical piece of infrastructure managed by the state regulatory agency, OWRB. With its stone core and soil foundation, this dam plays a crucial role in protecting the surrounding community from the impacts of high water events. However, with its last inspection dating back to 1980 and no recent updates on emergency preparedness, there is a pressing need to ensure that this structure is adequately maintained and equipped to handle the challenges of a changing climate.

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.
