Summary
Completed in 1960, this Earth-type dam serves multiple purposes including fire protection, stock, and small fish pond. With a dam height of 20 feet and a storage capacity of 67 acre-feet, it provides essential water resources for the local area.
Situated on the Antelope Coulee river, Daniel #1 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. With a maximum discharge of 130 cubic feet per second and a drainage area of 2.97 square miles, this dam plays a crucial role in mitigating flood risks and providing water for various needs. Despite not being under the jurisdiction of a federal agency, the dam is inspected, permitted, and regulated by the state of Montana to ensure its safety and functionality.
As a key infrastructure for water resource management and climate resilience in Hill County, Montana, Daniel #1 stands as a symbol of effective collaboration between private owners, state agencies, and design professionals. Its strategic location, multiple purposes, and low hazard potential make it a valuable asset for the community, highlighting the importance of sustainable water management practices in the face of changing climate conditions.

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.
