Summary
Built in 1960 by the USDA NRCS, this earth dam stands at a height of 20 feet and has a length of 850 feet. With a storage capacity of 106 acre-feet, the dam serves the primary purpose of irrigation and has a normal storage level of 45 acre-feet.
Managed by the DNRC, Morris #2 is classified as having low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The spillway of the dam is 40 feet wide, with a maximum discharge of 180 cubic feet per second. While the dam has not been inspected recently, it is subject to state regulation, inspection, and enforcement, ensuring its safety and compliance with regulatory standards.
Located in Congressional District 00 of Montana, Morris #2 plays a crucial role in providing water for agricultural purposes in the region. With its modest storage capacity and relatively low hazard potential, the dam represents a vital piece of infrastructure for water resource management in Toole County.

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.
