About this dam

Northgate Dam 2

Northgate Dam 2, located in Burke, North Dakota, is a local government-owned structure designed by NDSWC to regulate Stoney Run Creek. Completed in 1968, this earth dam stands at a height of 35 feet and has a maximum storage capacity of 4,200 acre-feet, serving primarily for recreational purposes with a surface area of 152 acres. The dam also features an uncontrolled spillway with a width of 200 feet.

Despite being classified as having a significant hazard potential, Northgate Dam 2 is rated as 'Not Rated' in terms of its condition assessment. The dam underwent structural modifications in 1979 and is equipped with two slide (sluice gate) outlet gates. It is regularly inspected by the North Dakota State Water Commission, which has jurisdiction over its regulation, permitting, inspection, and enforcement. The risk assessment for the dam is moderate, with a DSAC assigned date currently unspecified.

Water resource and climate enthusiasts would find Northgate Dam 2 to be an intriguing structure due to its historical significance, design features, and regulatory oversight. With its location in a picturesque area and its role in providing recreational opportunities, this earth dam serves as a vital component of the local water management infrastructure. Understanding the complexities and management strategies associated with Northgate Dam 2 can provide valuable insights into the intersection of water resource development, public safety, and environmental stewardship in North Dakota.

Condition Assessment

Satisfactory
No 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.
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.
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.

Hazard Potential Classification

High
Dams 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, environmental 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.

FAQ

About Northgate Dam 2

Where does the data for Northgate Dam 2 come from?

Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.

What does the Significant hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
