Summary
This lagoon is regulated by the North Dakota State Water Commission and serves a primary purpose of "Other". With a dam height of 13 feet, the lagoon has a storage capacity of 95.2 acre-feet and covers a surface area of 16.1 acres. Despite its low hazard potential, the condition assessment for Stanley Lagoon Cell 2 is currently listed as "Not Rated".
Operated by the local government, this lagoon plays a crucial role in water management within the region. Although lacking certain detailed information such as the year of completion and specific dam types, Stanley Lagoon Cell 2 remains a significant infrastructure for the community. As a part of the St. Paul District, this lagoon contributes to the overall water resource management efforts in North Dakota.
While the emergency preparedness and risk assessment aspects of Stanley Lagoon Cell 2 are not fully documented, the lagoon's presence and functionality are essential for maintaining water quality and quantity in the area. With its strategic location and regulated status, this lagoon serves as a vital component of the local water resource and climate resilience strategies.

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.
