Bear Creek Watershed Site 23 dam
Bear Creek Watershed Site 23
Located in the Bear Creek Watershed of Winneshiek County, Iowa, Site 23 is a flood risk reduction structure designed by the USDA NRCS and completed in 2000. This earth dam stands at a height of 32 feet and spans 545 feet, with a maximum storage capacity of 46 acre-feet. The primary purpose of this dam is flood risk reduction, serving the community of Quandahl by protecting against potential inundation from TR- North Bear Creek.
Managed by the Iowa DNR, this low hazard potential structure is state-regulated and regularly inspected for safety and compliance. With a drainage area of 0.28 square miles and a surface area of 2.4 acres, Site 23 plays a crucial role in managing water resources in the region. Although the risk assessment is moderate, the dam's condition is not currently rated, and emergency action plans are yet to be fully developed. Nonetheless, with its strategic location and design, this site is a key component in the overall watershed management strategy for the area.
Overall, Bear Creek Watershed Site 23 is an essential piece of infrastructure that contributes to the overall water resource management and climate resilience efforts in Winneshiek County. Through its flood risk reduction capabilities and regulated operation, this structure ensures the safety and protection of the surrounding community, highlighting the importance of sustainable water resource management practices in mitigating the impacts of extreme weather events 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 Bear Creek Watershed Site 23
Where does the data for Bear Creek Watershed Site 23 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.
