Summary
The dam stands at a height of 28 feet with a length of 880 feet, providing a storage capacity of 160 acre-feet and a drainage area of 0.45 square miles. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition and lacks an Emergency Action Plan (EAP) or detailed risk management measures.
With a spillway width of 40 feet and a maximum discharge of 619 cubic feet per second, Dd No 4-11 plays a crucial role in managing floodwaters and protecting the surrounding area from potential inundation. However, the dam's lack of state regulation, inspection, and enforcement raises concerns about its long-term safety and maintenance. Given its location in a high-risk flood zone, it is essential for local authorities to prioritize the assessment and improvement of Dd No 4-11 to ensure its continued effectiveness in flood risk reduction and climate resilience efforts.
As water resource and climate enthusiasts monitor the evolving challenges posed by extreme weather events and changing hydrological patterns, the condition and management of infrastructure like Dd No 4-11 become increasingly significant. By addressing the existing gaps in inspection, maintenance, and emergency preparedness, stakeholders can enhance the dam's resilience to climate impacts and strengthen its role in safeguarding communities and ecosystems along the Robidoux Creek.

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.
