Long Lake Nwr - G12 Marsh dam
Long Lake Nwr - G12 Marsh
Long Lake Nwr - G12 Marsh, located in Burleigh, North Dakota, is a federal-owned water resource managed by the USFWS. This marsh serves multiple purposes including fire protection, stock, and small fish pond. Constructed in 1991, the earth dam stands at a height of 6.5 feet and has a normal storage capacity of 129 acre-feet with a maximum storage of 500 acre-feet. The controlled spillway is 30 feet wide, and the outlet gate is a vertical lift.
Despite being rated as having a low hazard potential, Long Lake Nwr - G12 Marsh has a very high risk assessment score of 1. The condition assessment is not rated, and there is no information available on the emergency action plan or risk management measures. The dam does not fall under the jurisdiction of the USACE and is regulated by the NDSWC. With its strategic location on Apple Creek-TR, this marsh plays a crucial role in water resource management in the region.
Water resource and climate enthusiasts will appreciate the significance of Long Lake Nwr - G12 Marsh as a vital ecosystem and water source in North Dakota. Its role in fire protection, wildlife habitat, and water storage makes it a crucial part of the landscape. While the dam is currently considered to have a low hazard potential, the high risk assessment score underscores the importance of monitoring and maintaining this infrastructure to ensure the safety and sustainability of the surrounding environment.
Dam data reference
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.

About Long Lake Nwr - G12 Marsh
Where does the data for Long Lake Nwr - G12 Marsh 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 Low 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.
