Summary
This earth dam stands at a height of 20 feet and spans a length of 1240 feet, with a storage capacity of 148 acre-feet. Situated on TR-Frazier Creek, this structure serves the primary purpose of irrigation, with a low hazard potential and a state-regulated status ensuring regular inspection and enforcement by the Montana DNRC.
Despite being not rated for its condition assessment, Bateman #1 remains a crucial water resource in the region with a normal storage capacity of 51 acre-feet and a maximum discharge rate of 500 cfs. The dam's spillway width of 100 feet and location in a drainage area of 21.02 square miles highlight its importance in managing water flow and ensuring sustainable irrigation practices for local agriculture. With a designated emergency action plan yet to be prepared, continued monitoring and maintenance are essential to safeguard the dam's structural integrity and prevent potential risks in the future.
In the Congressional District 00 of Montana, represented by Greg Gianforte (R), Bateman #1 stands as a vital infrastructure supporting the local community's agricultural needs. With its strategic location and design by the Natural Resources Conservation Service, this dam plays a crucial role in water management while serving as a testament to the collaborative efforts in ensuring sustainable water resources 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.
