Frank Riley Dam dam
Frank Riley Dam
Frank Riley Dam, located in Lucas, Iowa, is a private dam designed by the USDA NRCS for grade stabilization purposes. Completed in 2017, this earth dam stands at a height of 32 feet and has a length of 392 feet, with a storage capacity of 32 acre-feet. Serving multiple purposes including grade stabilization, recreation, and water supply, the dam plays a crucial role in managing water resources in the area.
With a low hazard potential and a moderate risk assessment rating, Frank Riley Dam is regulated by the Iowa DNR and undergoes regular inspections to ensure its safety and effectiveness. Despite not having a condition assessment rating, the dam is deemed to meet guidelines for emergency action plans, although specific details on preparedness and contacts are not provided in the data. The dam's spillway type is uncontrolled, with a spillway width of 20 feet, and it is part of the Kansas City District under Congressional District 02 in Iowa.
Overall, Frank Riley Dam stands as an important infrastructure for water management in Clarke County, Iowa, contributing to grade stabilization efforts and providing recreational opportunities for the local community. With its strategic location near the Trib to North Hoosier Creek, the dam serves as a vital resource for water supply and contributes to the overall environmental sustainability of the region. Despite its low hazard potential, ongoing monitoring and maintenance ensure the continued safety and functionality of this essential water resource infrastructure.

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 Frank Riley Dam
Where does the data for Frank Riley Dam 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.
