About this dam

Lake Waltanna

Lake Waltanna in Sedgwick, Kansas, is a private water resource managed by the Kansas Department of Agriculture. Built by the USA WPA, this buttress dam serves multiple purposes including fire protection, stock, and small fish pond. With a dam height of 29 feet and a hydraulic height of 23 feet, Lake Waltanna has a maximum storage capacity of 228 acre-feet and a normal storage of 158 acre-feet. The low hazard potential of the dam makes it a safe and reliable source of water for the surrounding area.

Located in the city of Oxford, Lake Waltanna is fed by Afton Creek-TR and has a spillway width of 100 feet. Despite not being rated for condition assessment, the dam has a history of regular inspections and maintenance by the state regulatory agency. With a maximum discharge of 4426 cubic feet per second, the dam plays a crucial role in managing water levels and protecting the local ecosystem. Although the dam does not have an Emergency Action Plan in place, its low hazard potential and solid construction make it a valuable asset for water resource and climate enthusiasts in the region.

Overall, Lake Waltanna is a well-maintained private water resource with a primary focus on fire protection and stock management. Its strategic location in Sedgwick County, Kansas, and the efficient regulatory oversight by the state Department of Agriculture ensure the safety and sustainability of the dam. Water and climate enthusiasts can appreciate the functionality and importance of Lake Waltanna in providing essential services to the community while also preserving the natural environment of the area.

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 Lake Waltanna

Where does the data for Lake Waltanna 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.
