Summary
It serves multiple purposes, including fire protection, stock, and small fish pond management. With a height of 21 feet and a length of 700 feet, the dam has a storage capacity of 158 acre-feet and a drainage area of 1.88 square miles. The dam is regulated by the DNRC and has a low hazard potential, with a moderate risk assessment rating.
The dam on TR-East Fork Sand Creek is under the jurisdiction of the state of Montana and has state permitting, inspection, and enforcement in place. It is part of the Omaha District and falls under Congressional District 00, represented by Greg Gianforte. The primary source agency for this structure is the state of Montana, with the NRCS as the designer. The dam's primary purpose is to provide essential functions for the local community while also serving as a means of water resource management in the area.
While the condition of F Whitmus #2 is currently not rated, it is essential to note that the dam has not been modified since its completion. With a spillway width of 100 feet and a maximum discharge of 1000 cubic feet per second, the dam is equipped with an uncontrolled spillway. The risk assessment for the dam is moderate, indicating the need for ongoing monitoring and risk management measures to ensure the safety and functionality of the structure for both water resource and climate enthusiasts in the area.

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.
