Audubon Nwr-Impoundment#2 Dam
Audubon Nwr-Impoundment#2
Audubon Nwr-Impoundment#2 is a federally owned structure located in McLean, North Dakota, specifically in the city of N. Managed by the USFWS, this fish and wildlife pond was completed in 1979 with a dam height of 13 feet and a storage capacity of 450 acre-feet. The primary purpose of this earth dam is to provide habitat for various species of fish and wildlife in the area, making it a vital resource for conservation efforts in North Dakota.
With a surface area of 110 acres, Audubon Nwr-Impoundment#2 plays a crucial role in maintaining the ecological balance of Lake Audubon-TR. Despite its low hazard potential, the structure is regulated by the NDSWC and undergoes regular inspections and enforcement measures to ensure its integrity and safety. While the dam does not have a spillway, its risk assessment still highlights a high risk (2), indicating the importance of proper management and maintenance to prevent any potential hazards.
As a key component of the St. Paul District, Audubon Nwr-Impoundment#2 stands as a testament to the commitment of federal agencies towards wildlife conservation and environmental protection. With its strategic location and purposeful design, this structure serves as a valuable asset for water resource and climate enthusiasts, offering a glimpse into the intersection of sustainable infrastructure and biodiversity preservation in North Dakota.

About Audubon Nwr-Impoundment#2
Where does the data for Audubon Nwr-Impoundment#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 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 below 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.

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.
