Little Dam 3322 dam
Little Dam 3322
Little Dam 3322, located in Johnson, Nebraska, along Turkey Creek, was completed in 1980 with a primary purpose of flood risk reduction. This privately owned earth dam stands at a height of 25.4 feet and has a storage capacity of 35.1 acre-feet, providing crucial protection to the surrounding area. With a low hazard potential and a condition assessment that is currently not rated, Little Dam 3322 is a key infrastructure for managing water resources in the region.
Managed by the Nebraska Department of Natural Resources, Little Dam 3322 undergoes regular inspections to ensure its structural integrity and functionality. With a drainage area of 0.06 square miles and a normal storage capacity of 13 acre-feet, this dam plays a vital role in mitigating the impact of potential flooding events. While the dam has not been modified in recent years and lacks specific spillway details, its presence is essential for safeguarding the local community from water-related risks.
Congressional District 03, Nebraska, represented by Adrian Smith, relies on the protection provided by Little Dam 3322 to manage the flow of Turkey Creek and prevent potential flooding disasters. As climate change continues to impact water resources, the importance of dams like Little Dam 3322 in flood risk reduction and water management strategies becomes increasingly significant. This privately owned structure stands as a testament to the collaborative efforts between state agencies and private owners in safeguarding communities against the challenges of a changing climate.

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 Dam 3322
Where does the data for Little Dam 3322 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.
