Summary
Constructed in 1952, this earth dam stands at a height of 23 feet and spans a length of 552 feet, with a storage capacity of 194 acre-feet. Despite its relatively low hazard potential, Dodd is classified as having a poor condition assessment, indicating a need for maintenance and improvements to ensure its continued functionality.
The dam features an uncontrolled spillway with a width of 140 feet and a single valve outlet gate. With a moderate risk assessment rating, Dodd is in need of updated emergency action plans and risk management measures to mitigate potential hazards. Although its drainage area and maximum discharge are listed as zero, the dam's location and structural integrity are crucial considerations for water resource and climate enthusiasts interested in the sustainable management of water infrastructure in the region.
Ensuring the safety and efficiency of Dodd is paramount, given its role in supporting agricultural irrigation in the area. With its proximity to Decker, MT, and the oversight of regulatory agencies such as the SEO in Wyoming, ongoing inspections and maintenance are essential to address the dam's current poor condition assessment. As stakeholders work towards enhancing the resilience of water resources in the region, addressing the maintenance needs of Dodd will be crucial to safeguarding its operational capacity and mitigating potential risks associated with its aging 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.
