Summary
Dam #2, also known as Niagara Twp. Dam #2 (East), is a local government-owned dam located in Grand Forks, North Dakota. Built in 1935 by FERA, this earth dam stands at a height of 23 feet and stretches 300 feet in length. The primary purpose of the dam is for recreation, with a normal storage capacity of 120.8 acre-feet and a maximum storage of 243 acre-feet.
Managed by the North Dakota State Water Commission, Niagara Twp. Dam #2 is regulated, inspected, and enforced by the state. Despite its low hazard potential and moderate risk level, the dam has not been rated for its condition assessment. It features an uncontrolled spillway and has no outlet gates. The dam is situated on the North Branch Turtle River-TR, with a drainage area of 2.9 square miles and a surface area of 16 acres.
While the dam has not been modified in recent years and does not have an emergency action plan in place, its risk management measures are not specified. With its historical significance and role in providing recreational opportunities, Niagara Twp. Dam #2 serves as an essential structure in the water resource management and climate resilience efforts of the region.

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.
