Troublesome Cr Watershed Site 86-4 dam
Troublesome Cr Watershed Site 86-4
Troublesome Cr Watershed Site 86-4 is a local government-owned dam located in Audubon, Iowa, specifically in the city of Brayton. Built in 1992 by the USDA NRCS, this earth dam serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. With a dam height of 33 feet and a length of 468 feet, it has a normal storage capacity of 17 acre-feet and a maximum storage of 56 acre-feet.
Situated on the TR-East Nishnabotna River, Troublesome Cr Watershed Site 86-4 has a low hazard potential and is classified as having a moderate risk level. Although its condition is currently not rated, the dam is regulated and inspected by the Iowa DNR, with state permitting, inspection, and enforcement in place. With its primary purpose being water resource management, this dam plays a crucial role in protecting the surrounding area from potential flooding events and ensuring a stable water supply for various uses.
Overall, Troublesome Cr Watershed Site 86-4 stands as a vital infrastructure for water management in Audubon, Iowa, demonstrating the collaborative efforts between local government and federal agencies like the USDA NRCS. With its strategic location on the TR-East Nishnabotna River, this dam effectively mitigates flood risks while providing essential water resources for fire protection, agriculture, and wildlife support. As climate change continues to impact water resources, the importance of maintaining and monitoring structures like Troublesome Cr Watershed Site 86-4 becomes increasingly critical for the resilience of communities and ecosystems in the region.
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 Troublesome Cr Watershed Site 86-4
Where does the data for Troublesome Cr Watershed Site 86-4 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.
