Dd No 123 dam
Dd No 123
Dd No 123 is a local government-owned dam located in Jackson, Kansas, with a primary purpose of flood risk reduction. Built in 1995, this earth dam stands at a height of 31.8 feet and spans a length of 1050 feet, with a storage capacity of 652.2 acre-feet. The dam is regulated by the Kansas Department of Agriculture and is equipped with an uncontrolled spillway with a width of 40 feet, capable of discharging up to 1200 cubic feet per second.
Despite being classified as having a low hazard potential and not yet rated for its condition assessment, Dd No 123 presents a moderate risk level. With a drainage area of 1.43 square miles and a surface area of 15.4 acres, this dam plays a crucial role in managing floodwaters in the Cross Creek-TR watershed. Although it has not been inspected since October 2005, the dam is subject to state enforcement and permitting, ensuring its continued safety and functionality for the surrounding community.
For water resource and climate enthusiasts, Dd No 123 serves as a significant flood control structure in Kansas, contributing to the overall resilience of the region against potential water-related disasters. Its strategic location and design, coupled with state regulatory oversight and operational protocols, highlight the importance of infrastructure management in safeguarding communities and ecosystems from the impacts of extreme weather events.
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 Dd No 123
Where does the data for Dd No 123 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.
