Nyroca Flats Wma dam
Nyroca Flats Wma
Nyroca Flats WMA, located in Lyon County, Minnesota, offers a unique and vital habitat for fish and wildlife within its 54-acre surface area. Managed by the Minnesota Department of Natural Resources, this State-regulated water management area features an Earth dam with a height of 7 feet and a hydraulic height of 3.3 feet. The dam, designed by Bolton & Menk, serves as a crucial source of water storage with a capacity of 500 acre-feet.
The Redwood River-TR flows through Nyroca Flats WMA, providing a scenic backdrop for water and climate enthusiasts to observe the diverse ecosystem supported by this fish and wildlife pond. With a low hazard potential and a satisfactory condition assessment as of 2015, the dam at Nyroca Flats WMA is regularly inspected and maintained to ensure its safety and longevity. The area's proximity to Russell, Minnesota, makes it easily accessible for visitors interested in exploring the natural beauty and conservation efforts at this site.
Overall, Nyroca Flats WMA stands as a testament to the importance of responsible water resource management in supporting biodiversity and ecological balance. As a State-regulated area with a primary purpose of enhancing fish and wildlife habitats, this location offers a glimpse into the interconnected relationship between water resources, climate conditions, and the diverse array of species that rely on these habitats for survival. Visitors to Nyroca Flats WMA can witness firsthand the critical role that sustainable water management plays in preserving natural ecosystems for future generations to enjoy.

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 Nyroca Flats Wma
Where does the data for Nyroca Flats Wma 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.
