30th Street Detention Basin dam
30th Street Detention Basin
The 30th Street Detention Basin in Minot, North Dakota, is a crucial flood risk reduction structure designed by Ackerman Estvold and owned by the local government. Situated along the Second Larson Coulee, this earth dam has a height of 24.5 feet and a storage capacity of 284.9 acre-feet. With a surface area of 31.7 acres and a drainage area of 8 square miles, this basin plays a vital role in mitigating flood impacts in the region.
Managed by the North Dakota State Water Commission, the 30th Street Detention Basin is state-regulated and receives regular inspections, ensuring its functionality and effectiveness in flood control. With a significant hazard potential, this structure is designed to withstand and manage high water levels during extreme weather events. While the condition assessment is currently not rated, the basin's primary purpose of flood risk reduction highlights its importance in safeguarding the community from potential water-related disasters.
As a key component in the local flood management system, the 30th Street Detention Basin serves as a critical infrastructure in protecting the residents of Minot and surrounding areas from the devastating impacts of flooding. With its strategic location and design, this basin exemplifies proactive measures taken to address water resource challenges and climate-related risks in the region.
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 30th Street Detention Basin
Where does the data for 30th Street Detention Basin 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.
