Westside Subwatershed Site 3-2 dam
Westside Subwatershed Site 3-2
Westside Subwatershed Site 3-2, located in Correctionville, Iowa, is a flood risk reduction structure designed by USDA NRCS in 2003. This earth dam stands 34 feet tall and spans 440 feet along TR-Bacon Creek, offering a storage capacity of 124 acre-feet. With a primary purpose of flood risk reduction, this structure is regulated by the Iowa DNR and falls under state jurisdiction.
The dam's spillway is uncontrolled and measures 3 feet in width, with a hazard potential rated as low and a moderate risk assessment score of 3. Despite its low hazard potential, the condition of the dam is currently not rated, and it has not undergone recent inspections or maintenance evaluations. The site's maintenance and emergency preparedness measures, including the existence of an Emergency Action Plan (EAP) and updated contact information, are not documented in the available data. While the risk associated with Westside Subwatershed Site 3-2 is deemed moderate, its management measures and risk characterization details remain unspecified.
In summary, Westside Subwatershed Site 3-2 serves as a vital flood risk reduction structure along TR-Bacon Creek in Iowa, constructed with a focus on enhancing water resource management in the region. The dam's earth construction and substantial storage capacity underline its significance in mitigating potential flooding events. However, the lack of recent assessments and emergency preparedness documentation highlight the need for continued monitoring and maintenance to ensure the structure's effectiveness in safeguarding the local community against flood hazards.

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 Westside Subwatershed Site 3-2
Where does the data for Westside Subwatershed Site 3-2 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.
