Summary
is a privately owned dam located in Blaine, Montana, specifically in the city of LOHMAN. Constructed in 1960 by the USDA NRCS, this earth dam stands at 8 feet tall and spans 300 feet in length, with a storage capacity of 77 acre-feet. The dam serves primarily for recreation purposes, providing a serene spot along the TR-MILK RIVER for outdoor enthusiasts in the area.
Managed by the DNRC, Krott, L. is regulated and inspected by the state of Montana to ensure its safety and functionality. With a low hazard potential and a current condition assessment of "Not Rated," the dam is considered to be in stable condition. While there is no recent data on the last inspection date or emergency action plan preparedness, the dam continues to provide valuable recreational opportunities for the community.
Located in Congressional District 00, Montana, Krott, L. is overseen by the Natural Resources Conservation Service and falls under the jurisdiction of the state regulatory agency. With a spillway width of 75 feet and a maximum discharge of 98 cubic feet per second, the dam is designed to manage water flow effectively. Despite not having a designated emergency action plan or updated inundation maps, Krott, L. remains a key feature in the local landscape, offering both beauty and functionality for water resource and climate enthusiasts to enjoy.

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.
