Dodecanese dam
Dodecanese
Dodecanese, located in Loma, Chouteau, Montana, is a private earth dam completed in 1967 with a primary purpose of fire protection, stock, or small fish pond. With a height of 10 feet and a length of 325 feet, Dodecanese has a storage capacity of 52 acre-feet, providing a vital water resource for the area. Situated on Dugout Coulee, this dam is state-regulated by the Department of Natural Resources and Conservation (DNRC) with regular inspections and enforcement to ensure its safety and functionality.
Despite being classified as having a low hazard potential, Dodecanese's condition assessment is currently marked as 'Not Rated', signaling a need for further evaluation. The dam has not undergone a recent inspection, and its emergency action plan (EAP) status and risk management measures are also not updated. Although the dam has not been modified in recent years, there is a lack of information on its risk assessment and potential hazards, highlighting the importance of regular monitoring and maintenance to safeguard the surrounding community and water resources. As a crucial infrastructure for fire protection and water storage, Dodecanese plays a significant role in the local ecosystem and climate resilience efforts in the region.
Located in Congressional District 00, Montana, Dodecanese is part of the larger network of dams and water structures overseen by the Omaha District of the US Army Corps of Engineers. With its strategic location and purpose, Dodecanese contributes to the sustainable management of water resources in the area, supporting agricultural activities, wildlife habitat, and emergency preparedness. As climate change continues to impact water availability and quality, the maintenance and regulation of dams like Dodecanese become essential for ensuring the resilience of communities and ecosystems in the face of changing environmental conditions.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Dodecanese
Where does the data for Dodecanese come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
