About this dam

Valley Falls Water Supply Dam

Valley Falls Water Supply Dam, located in Valley Falls, Kansas, serves as a vital resource for the local community as a water supply structure. Built in 1954, this buttress dam stands at a height of 32 feet with a structural height of 36 feet, and a length of 560 feet. It has a storage capacity of 108 acre-feet and is situated on Walnut Creek-TR, within the jurisdiction of the Kansas Department of Agriculture.

Despite its age, the dam has a low hazard potential and has not been rated for its current condition. The last inspection was conducted in November 1992, indicating a need for updated assessment and risk management measures. With a maximum discharge capacity of 450 cubic feet per second and a spillway width of 25 feet, the dam plays a crucial role in maintaining water supply and managing flood control in the region. The dam's location in Jefferson County, Kansas adds to its significance in the local water resource infrastructure.

Overall, Valley Falls Water Supply Dam stands as a key asset for the community, providing essential water supply functions while warranting continued evaluation and maintenance to ensure its long-term reliability and safety. With the involvement of the Kansas Department of Agriculture and the Rock Island District, efforts are directed towards preserving the dam's integrity and enhancing its operational capabilities for the benefit of Valley Falls and its surrounding areas.

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.

FAQ

About Valley Falls Water Supply Dam

Where does the data for Valley Falls Water Supply Dam 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.
