Twin Parks 8 dam
Twin Parks 8
Twin Parks 8, also known as Trout Creek Dry, is a vital water resource structure located in Iowa County, Wisconsin. Constructed in 1963 by the USDA NRCS, this earth dam serves primarily for debris control and flood risk reduction along the Trout Creek. With a height of 33 feet and a length of 637 feet, Twin Parks 8 has a storage capacity of 970 acre-feet and a maximum discharge rate of 212 cubic feet per second.
Managed by the Wisconsin Department of Natural Resources (WIDNR), Twin Parks 8 is regulated, inspected, and enforced by state authorities to ensure its structural integrity and functionality. Despite being classified as low hazard potential with fair condition assessment, the dam poses a moderate risk due to its age and the surrounding environmental factors. Emergency action plans and risk management measures are in place to mitigate any potential threats and ensure the safety of nearby communities.
Water resource and climate enthusiasts can appreciate the significant role that Twin Parks 8 plays in managing flood risks and protecting the local environment. Its presence along the Trout Creek provides a crucial line of defense against debris and potential flooding, showcasing the importance of sustainable water infrastructure in safeguarding communities and ecosystems. With ongoing monitoring and maintenance efforts, Twin Parks 8 continues to serve as a vital asset for water resource management in Iowa County, Wisconsin.
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 8
Where does the data for Twin Parks 8 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.
