Twin Parks 10 dam
Twin Parks 10
Twin Parks 10, also known as White's, is a vital flood risk reduction structure located in Wisconsin, specifically in Iowa County. Designed by the USDA NRCS and completed in 1966, this Earth-type dam stands at a height of 32 feet and spans 598 feet in length. Its primary purpose is to mitigate flood risks and control debris in the TR Mill Creek watershed, with a storage capacity of 200 acre-feet.
Managed and regulated by the Wisconsin Department of Natural Resources, Twin Parks 10 has a low hazard potential and is assessed to be in fair condition as of May 2020. Despite its moderate risk rating, the dam has not been modified in recent years and is subject to regular inspections every 10 years to ensure its structural integrity. The dam is equipped with an uncontrolled spillway, capable of discharging up to 130 cubic feet per second during heavy rainfall events.
For water resource and climate enthusiasts, Twin Parks 10 presents an intriguing case study of how local government agencies collaborate with federal entities like the USDA NRCS to manage and maintain critical infrastructure for flood control and environmental protection. With its strategic location in the TR Mill Creek watershed, this dam plays a crucial role in safeguarding communities downstream from potential flood events, highlighting the importance of proactive risk management and infrastructure maintenance in the face of changing climatic conditions.
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 Twin Parks 10
Where does the data for Twin Parks 10 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.
