Summary
With a dam height of 35 feet and a storage capacity of 136 acre-feet, this low hazard potential structure serves multiple functions for the local community. Despite being not rated for its condition, the dam is regularly inspected, permitted, and regulated by the Montana Department of Natural Resources and Conservation (DNRC).
The dam's strategic location in MARMARTH NORTH DAKOTA, just 87 miles away from the Omaha District of the US Army Corps of Engineers, highlights its importance in providing essential water resources for various uses. Although specific details like surface area, drainage area, and spillway type are not available, the dam's ability to store and regulate water flow in TR-BOX ELDER CREEK contributes to the overall water management efforts in the region. With a normalized storage capacity of 50 acre-feet, La Ze #1 plays a crucial role in maintaining water security and supporting local ecosystems.
While the dam's emergency action plan (EAP) status and risk assessment information are unknown, its presence underscores the significance of small-scale water infrastructure in sustaining agricultural, recreational, and environmental interests. As climate change continues to impact water resources, structures like La Ze #1 demonstrate the importance of proactive management and regulation to ensure the resilience of water systems in the face of evolving climatic conditions. For water resource and climate enthusiasts, La Ze #1 serves as a case study in the intersection of infrastructure, water management, and environmental stewardship.

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.
