North Pigeon Cr Watershed Site 4-1 dam
North Pigeon Cr Watershed Site 4-1
North Pigeon Cr Watershed Site 4-1 in Pottawattamie, Iowa, is a vital water resource managed by the local government with assistance from the USDA NRCS. This earth dam, completed in 1971, serves multiple purposes including fire protection, stock watering, and small fish pond management. With a dam height of 57 feet and a storage capacity of 302 acre-feet, this structure plays a crucial role in flood risk reduction for the surrounding area.
Located on TR-PIGEON CREEK, this dam covers a drainage area of 0.39 square miles and has a surface area of 11.9 acres. Despite being rated as having a low hazard potential, it is considered to have a moderate risk level. Regular inspection and maintenance by the Iowa DNR ensure that the dam remains in good condition to fulfill its functions effectively. The site is also in compliance with state regulations, including permitting, inspection, and enforcement requirements.
North Pigeon Cr Watershed Site 4-1 is an essential component of the water management infrastructure in the region, contributing to both water supply and flood mitigation efforts. With its strategic location and design, this dam stands as a testament to effective collaboration between local government agencies and federal partners in ensuring the sustainability and safety of water resources in the area. For water resource and climate enthusiasts, this site serves as a prime example of responsible water management practices in action.
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 North Pigeon Cr Watershed Site 4-1
Where does the data for North Pigeon Cr Watershed Site 4-1 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.
