Crookston Rock Rapids dam
Crookston Rock Rapids
Crookston Rock Rapids is a rockfill dam located in Polk County, Minnesota, along the Red Lake River. Completed in 2007, this structure serves the primary purpose of grade stabilization and has a height of 11 feet, providing a storage capacity of 60 acre-feet. With a low hazard potential and a drainage area of 5,356 square miles, this dam plays a crucial role in managing water resources in the region.
Managed by the local government, Crookston Rock Rapids is regulated, permitted, inspected, and enforced by the Minnesota Department of Natural Resources, ensuring its compliance with state regulations and safety standards. Despite not being rated for its condition assessment, the dam has a regular inspection frequency of every 8 years. Its emergency action plan status and risk assessment measures are currently not available, but the structure's design and purpose contribute to mitigating potential risks and enhancing water resource management.
Located within the Omaha District of the US Army Corps of Engineers, Crookston Rock Rapids stands as a critical infrastructure for flood control and water resource management along the Red Lake River. With its stable design, low hazard potential, and state-regulated operation, this dam plays a vital role in protecting the surrounding communities and environment from potential water-related disasters while ensuring sustainable water resource utilization in the region.

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.
Plan around the weather

About Crookston Rock Rapids
Where does the data for Crookston Rock Rapids 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.
