Little Whiskey Subwatershed Site M-1 dam
Little Whiskey Subwatershed Site M-1
Located in Woodbury County, Iowa, the Little Whiskey Subwatershed Site M-1 is a local government-owned dam designed by the USDA NRCS. Completed in 1984, this earth dam stands at a height of 37 feet and spans a length of 650 feet, providing flood risk reduction and other purposes for the surrounding area. With a storage capacity of 162 acre-feet and a drainage area of 1.41 square miles, this dam plays a crucial role in managing water resources in the region.
Managed by the Iowa DNR, this dam is regulated, permitted, inspected, and enforced by the state, ensuring its structural integrity and safety. Despite being categorized as having a low hazard potential, the dam is deemed to have a moderate risk level. With no condition assessment rating available, the dam's risk management measures and emergency action plans are yet to be fully evaluated. Overall, the Little Whiskey Subwatershed Site M-1 serves as a vital infrastructure for water resource management and climate resilience in the area.
Situated in Luton, Iowa, along the TR- Little Whiskey Creek, this dam not only helps in flood risk reduction but also contributes to the overall environmental health of the region. As a part of the Omaha District, the dam's primary purpose and design by the Natural Resources Conservation Service highlight the collaborative efforts of various agencies in safeguarding water resources and promoting sustainable development. With its robust construction and strategic location, the Little Whiskey Subwatershed Site M-1 stands as a testament to the importance of effective water management practices in combating the challenges posed by climate change.
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 Little Whiskey Subwatershed Site M-1
Where does the data for Little Whiskey Subwatershed Site M-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.
