Summary
Completed in 1963, this dam serves the primary purpose of irrigation, with a normal storage capacity of 55 acre-feet and a maximum discharge of 20 cubic feet per second. The dam stands at a height of 33.3 feet and has a hydraulic height of 30.6 feet, providing water storage for agricultural use in the region.
Situated on the DIV FROM STRAWBERRY CREEK, Henry Dam #2 is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and falls under state jurisdiction for permitting, inspection, and enforcement. With a low hazard potential and a condition assessment of "Not Rated," this dam plays a vital role in water resource management in the area. While it may not have a spillway type specified, the dam's spillway width of 100 feet ensures proper water release during periods of excess flow.
Water resource and climate enthusiasts will appreciate the strategic location and function of Henry Dam #2 in supporting agricultural irrigation in Toole County. As a key element of the local water infrastructure, this dam serves as a crucial resource for maintaining water supply and managing water flow in the region. With its long history of service and continued state regulation, Henry Dam #2 remains an essential component of sustainable water management in Montana.

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.
