Troublesome Cr Watershed Site 21-1 dam
Troublesome Cr Watershed Site 21-1
Troublesome Cr Watershed Site 21-1 in Cass County, Iowa is a vital water resource managed by the local government for fire protection, stock, and small fish pond purposes. Completed in 1987 by the USDA NRCS, this earth dam stands at a height of 35 feet and spans 760 feet, with a maximum storage capacity of 272 acre-feet. Situated along the TR- Troublesome Cr. stream, this dam covers a drainage area of 0.71 square miles and serves as a flood risk reduction measure for the community of Atlantic.
Despite its low hazard potential, Troublesome Cr Watershed Site 21-1 is not currently rated for its condition assessment, highlighting the need for ongoing monitoring and maintenance. The Iowa DNR plays a crucial role in regulating, inspecting, and enforcing state requirements for this dam, ensuring its operational safety and integrity. With a moderate risk assessment score of 3, it is essential for stakeholders to implement effective risk management measures to safeguard this important water infrastructure for the surrounding area.
As a significant component of the water management system in Cass County, Troublesome Cr Watershed Site 21-1 represents a critical asset for both water resource and climate enthusiasts. Its construction and maintenance by the USDA NRCS, along with state regulatory oversight by the Iowa DNR, demonstrate a collaborative effort to protect the community from flooding and provide essential water resources for various purposes. By staying informed and actively involved in the monitoring and maintenance of this dam, stakeholders can ensure its continued functionality and resilience in the face of changing environmental 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 Troublesome Cr Watershed Site 21-1
Where does the data for Troublesome Cr Watershed Site 21-1 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.
