Mpd No 21 dam
Mpd No 21
Mpd No 21, located in Elk County, Kansas, is a vital water supply infrastructure managed by the local government. This earth-type dam on Wildcat Creek was completed in 1983 and stands at a height of 41.6 feet, with a storage capacity of 7265 acre-feet. The dam serves the primary purpose of water supply, providing a normal storage capacity of 1500 acre-feet and covering a surface area of 185 acres.
Despite its fair condition assessment and high hazard potential, Mpd No 21 is regulated, permitted, inspected, and enforced by the Kansas Department of Agriculture to ensure its safety and functionality. The dam has a spillway width of 300 feet and a drainage area of 7.41 square miles, with a maximum discharge capacity of 17640 cubic feet per second. In the event of an emergency, the dam has a designated inspection frequency of 3 years to assess its structural integrity and risk management measures.
For water resource and climate enthusiasts, Mpd No 21 serves as a critical infrastructure for water supply in the region, highlighting the importance of proper regulation and maintenance to ensure its resilience against potential hazards. With its strategic location on Wildcat Creek and the involvement of various state agencies in its oversight, Mpd No 21 stands as a testament to the collaboration and commitment to safeguarding water resources for the community.
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 Mpd No 21
Where does the data for Mpd No 21 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 High 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.
