Summary

Dale Steward, P.E. Its primary purpose is flood risk reduction, with a height of 34 feet and a length of 1000 feet. Completed in 1995, this dam has a normal storage capacity of 54.02 acre-feet and a maximum storage capacity of 401.37 acre-feet, serving the Slate Creek-TR river/stream.

Despite being rated as having a low hazard potential and not yet assessed for condition, Dd No 35 is regulated, permitted, inspected, and enforced by the Kansas Department of Agriculture. The dam features an uncontrolled spillway with a width of 40 feet and no outlet gates. With a moderate risk assessment score of 3, there are currently no emergency action plans in place, but the dam meets regulatory guidelines and has not been modified since its completion.

Water resource and climate enthusiasts will find Dd No 35 an intriguing structure for flood risk management in the region, offering insight into dam design, functionality, and regulatory oversight. Its location in Toronto, Kansas, and association with the Kansas City District of the US Army Corps of Engineers make it a valuable asset for those interested in water infrastructure and management practices.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
