Innes Dam dam
Innes Dam
Innes Dam, located in Prairie, Montana, is a gravity dam with a height of 14 feet and a hydraulic height of 10 feet. Managed by the Bureau of Land Management, this federal structure on an unnamed drainage serves as a vital water resource in the area. With a storage capacity of 60.3 acre-feet and a surface area of 10.34 acres, the dam plays a crucial role in managing water supply and flood control in the region.
Although rated as having low hazard potential and its condition not yet assessed, Innes Dam is subject to periodic inspections every five years to ensure its structural integrity and functionality. Despite not having a designated primary purpose, the dam serves various roles in water management and conservation efforts. The dam's location at S28, 14N, 50E makes it a significant feature in the local landscape, contributing to the resilience of the surrounding ecosystem and providing valuable recreational opportunities for visitors interested in exploring the area's water resources and climate dynamics.
With its historical significance and contribution to water management in the region, Innes Dam stands as a testament to the importance of sustainable infrastructure in mitigating the impacts of climate change on water resources. As enthusiasts of water resource management and climate resilience, exploring the engineering and environmental aspects of Innes Dam offers valuable insights into the intricate balance between human development and natural ecosystems.

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 Innes Dam
Where does the data for Innes Dam 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.
