Stang Dam; Larry Reservoir Report
Last Updated: February 9, 2026
Stang Dam, also known as Wetland #1, is a privately owned earth dam located in Hettinger, North Dakota.
Summary
Built in 2003 by the USFWS, this dam serves multiple purposes including fire protection, stock watering, and a small fish pond. With a height of 11.9 feet and a storage capacity of 53.5 acre-feet, it covers a surface area of 6.8 acres and has a drainage area of 2.28 acres.
The dam is regulated by the North Dakota State Water Commission (NDSWC) and is inspected regularly to ensure its structural integrity. It has a low hazard potential and a moderate risk assessment rating of 3. The spillway type is uncontrolled with a width of 50 feet. The dam's primary purpose is to provide essential water resources for the surrounding area while also serving as a habitat for local wildlife.
Despite not being rated for its condition, Stang Dam; Larry continues to fulfill its intended functions effectively. With its strategic location on Tepee Creek-TR and the oversight of the NDSWC, this dam plays a crucial role in water resource management and climate resilience in North Dakota. Its presence underscores the importance of sustainable water infrastructure for both human and ecological needs.

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.
