Summary
Designed by USDA NRCS and completed in 1963, this earth dam stands at a height of 20 feet and spans 900 feet in length, with a storage capacity of 52 acre-feet. The primary purposes of this dam are for fire protection, stock, or small fish pond use.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Ed Styer #2 is regulated, permitted, inspected, and enforced by the state. Despite being classified as having a low hazard potential, this structure has a moderate risk assessment rating of 3, indicating a need for some level of risk management measures. The spillway is uncontrolled with a width of 200 feet, allowing for a maximum discharge of 350 cubic feet per second.
Climate and water resource enthusiasts will find Ed Styer #2 to be an intriguing case study in dam infrastructure, with its historical significance and ongoing management by state authorities. The structure's location in a rural area without a designated city adds to its mystique, offering a glimpse into the vital role of private dams in providing essential services such as fire protection and livestock water supply in remote regions. As efforts to address climate change and water scarcity continue to grow, understanding the complexities of these structures like Ed Styer #2 becomes increasingly important for ensuring sustainable water resource management practices.

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.
