North Pigeon Cr Watershed Site M dam
North Pigeon Cr Watershed Site M
Located in Pottawattamie County, Iowa, the North Pigeon Cr Watershed Site M is a vital water resource managed by the local government for fire protection, stock, and small fish pond purposes. Constructed in 1996 by the USDA NRCS, this earth dam stands at a height of 17 feet and spans a length of 1160 feet, providing a storage capacity of 64 acre-feet. With a drainage area of 6.66 square miles, this structure plays a crucial role in flood risk reduction along the North Pigeon Creek.
Managed by the Iowa DNR, this site is regulated, permitted, inspected, and enforced to ensure its safety and effectiveness. The dam, with a hazard potential rated as low, has not been assessed for its condition but is considered to have moderate risk. Despite lacking an emergency action plan (EAP) and inundation maps, the North Pigeon Cr Watershed Site M meets regulatory guidelines while operating under the Omaha District of the US Army Corps of Engineers.
For water resource and climate enthusiasts, the North Pigeon Cr Watershed Site M presents an intriguing case study of local government involvement in managing water resources for multiple purposes. With its strategic location in Crescent, Iowa, and its role in flood risk reduction, this site exemplifies the importance of sustainable water management practices in enhancing community resilience to natural disasters.
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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About North Pigeon Cr Watershed Site M
Where does the data for North Pigeon Cr Watershed Site M 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.
