Summary
With a height of 21 feet and a length of 1760 feet, the dam has a storage capacity of 245.42 acre-feet and covers a surface area of 6.74 acres. Despite its low hazard potential and not being regulated or inspected by the state, Dd No M-1 plays a crucial role in mitigating flood risks in the area.
Situated within the Tulsa District, Dd No M-1 stands as a testament to the dedicated efforts of local government agencies in safeguarding their communities against potential water-related disasters. While the dam's condition assessment is currently not rated, its construction and design have effectively served the region for over three decades. However, the lack of state regulatory oversight and inspection raises questions about the long-term maintenance and efficacy of the dam in the face of evolving climate patterns and water resource management challenges.
As water resource and climate enthusiasts, understanding the intricacies of structures like Dd No M-1 provides valuable insights into the intersection of infrastructure, environmental stewardship, and community resilience. With its unlisted foundation, unknown designer, and limited state involvement, this dam serves as a reminder of the diverse approaches to water management across different jurisdictions and the ongoing need for proactive monitoring and maintenance to ensure the safety and effectiveness of critical flood control infrastructure.

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.
