Summary
Managed by the Montana Department of Natural Resources and Conservation (DNRC), this earth dam stands at 20 feet in height and stretches 200 feet in length. With a storage capacity of 67 acre-feet, Gruszie serves as a crucial water resource along the TR-Peoples Creek, assisting in maintaining water levels for various uses in the region.
Despite being classified as having low hazard potential, Gruszie has not been officially rated for its condition assessment. The dam's emergency action plan status, risk assessment, and management measures remain unreported, indicating a need for further evaluation and potential updates. With Greg Gianforte representing Montana's Congressional District 00, the oversight and maintenance of Gruszie as part of the Omaha District will continue to be crucial for ensuring the safety and sustainability of this essential water infrastructure in the area. Enthusiasts of water resources and climate change should keep an eye on developments related to Gruszie to ensure its continued efficacy in serving the community.

Dam Data Reference
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.
