Dd No 22 dam
Dd No 22
Dd No 22, located in Alta Vista, Kansas, is a local government-owned earth dam designed by King Engineering in 2005 for flood risk reduction along the Kansas River. With a height of 34 feet and a length of 1550 feet, this dam provides a storage capacity of 463 acre-feet and covers a surface area of 9.97 acres. It has a spillway width of 40 feet and a maximum discharge capacity of 1923 cubic feet per second.
This dam is regulated by the Kansas Department of Agriculture and undergoes regular inspections, with the last one conducted in April 2019. Classified as having a significant hazard potential and a satisfactory condition assessment, Dd No 22 is considered to pose a moderate risk (level 3) according to the risk assessment. Although there are no outlet gates or associated structures, the dam serves its primary purpose effectively in reducing flood risks in the area.
Overall, Dd No 22 plays a vital role in protecting the surrounding areas from potential flooding events and demonstrates a commitment to water resource management and climate resilience by the local government in Wabaunsee County, Kansas. With its strategic location and design features, this dam serves as a crucial infrastructure for safeguarding lives and property in the region while preserving the ecological balance of the Kansas River watershed.

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 Dd No 22
Where does the data for Dd No 22 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 Significant 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.
