Twp Road 163 dam
Twp Road 163
Twp Road 163 is a vital infrastructure owned by the local government in Lyon County, Minnesota, designed by MNDOT for the primary purpose of flood risk reduction along Coon Creek. Completed in the year 2000, this buttress-type structure stands at a height of 23 feet and spans a length of 500 feet, with a maximum discharge capacity of 341 cubic feet per second. With a low hazard potential and a condition assessment that is currently not rated, Twp Road 163 plays a crucial role in protecting the surrounding area from potential flooding.
Located in Russell, Minnesota, Twp Road 163 not only serves as a flood risk reduction measure but also provides storage capacity of 91 acre-feet, with a normal storage level of 1 acre-foot. Despite being unlisted for foundations, this structure has a spillway width of 15 feet and is situated within the Omaha District of the USACE. With no state jurisdiction or permitting required, Twp Road 163 stands as a testament to effective flood management in the region, showcasing the collaboration between local government agencies and MNDOT in ensuring the safety and protection of the community.
For water resource and climate enthusiasts, Twp Road 163 represents a significant piece of infrastructure in the battle against potential flooding in Lyon County. With a focus on flood risk reduction and a low hazard potential, this structure stands as a key component in the overall water management system along Coon Creek. As an essential part of the local government's flood mitigation strategy, Twp Road 163 exemplifies the importance of proactive measures in safeguarding communities against natural disasters related to water resources and climate variability.
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 Twp Road 163
Where does the data for Twp Road 163 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.
