Summary
The dam stands at 16 feet high with a length of 300 feet, providing a storage capacity of 67 acre-feet. It has a low hazard potential and a moderate risk assessment rating. The dam has state jurisdiction and is regulated by DNRC, with permitting, inspection, and enforcement in place to ensure its safety and compliance.
This structure, owned privately, serves as a crucial water resource for the surrounding area, with a drainage area of 1.03 square miles and a maximum discharge capacity of 250 cubic feet per second. The spillway, uncontrolled in nature, has a width of 25 feet to manage excess water flow. Despite its condition not being rated, the dam continues to fulfill its intended purposes effectively. It is situated within Congressional District 00 of Montana, under the oversight of the Omaha District of the US Army Corps of Engineers.
Being a significant component of the local water management system, Hintz dam warrants attention from water resource and climate enthusiasts. Its design, construction, and operation showcase the importance of sustainable infrastructure for water storage and conservation. With proper regulatory measures in place and a commitment to regular inspections, this earth dam stands as a vital asset for fire protection, livestock, and aquatic life in the region.

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.
