Dd No 4-3 (Mapes) dam
Dd No 4-3 (Mapes)
Dd No 4-3 (Mapes) is a local government-owned dam located in Muscotah, Kansas, along the Muddy Creek-TR. Built in 1987 by Speaker & King, this earth dam stands at a height of 27 feet with a length of 610 feet, providing flood risk reduction and debris control for the surrounding area. With a storage capacity of 110 acre-feet and a drainage area of 0.18 square miles, the dam plays a crucial role in managing water flow and protecting the community from potential flooding events.
Despite being classified as having a low hazard potential, Dd No 4-3 (Mapes) is deemed to have a moderate risk level, indicating the importance of regular monitoring and maintenance. The dam features an uncontrolled spillway with a width of 48 feet and is not currently equipped with outlet gates. While its condition assessment is not rated, the dam has not undergone any recent modifications or inspections. It is essential for water resource and climate enthusiasts to stay informed about the risk management measures in place for Dd No 4-3 (Mapes) to ensure the safety and resilience of the community against potential hazards.
As part of the Kansas City District, Dd No 4-3 (Mapes) serves as a vital infrastructure for flood control in the region, with a primary purpose of reducing flood risks and protecting the surrounding area from potential inundation. The dam's location in Jackson County, Kansas, highlights its importance in managing water resources and maintaining the ecological balance of the local ecosystem. With a normal storage capacity of 29.6 acre-feet and a surface area of 4.86 acres, this dam plays a significant role in water conservation and flood mitigation efforts in the area, making it a key asset for water resource and climate enthusiasts to monitor and support.
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 4-3 (Mapes)
Where does the data for Dd No 4-3 (Mapes) 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.
