Summary
Completed in 1954 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along Grasshopper Creek. With a height of 34 feet and a length of 1490 feet, Zimmer Dd No I has a storage capacity of 930 acre-feet and covers a surface area of 0.6 acres.
Managed by the Kansas Department of Agriculture, Zimmer Dd No I is classified as a low hazard potential structure with a moderate risk assessment rating. Despite its age, the dam's condition assessment is currently not rated, and it has not been inspected recently. The dam features an uncontrolled spillway with a width of 160 feet and no outlet gates. While it does not have associated structures, Zimmer Dd No I plays a crucial role in protecting the surrounding area from potential flooding events.
As water resource and climate enthusiasts, the information about Zimmer Dd No I provides valuable insights into the infrastructure designed to mitigate flood risks in the region. The dam's location, dimensions, and purpose offer a glimpse into the efforts made by local authorities to safeguard communities and properties from potential water-related disasters. With its state-regulated status and historical significance in flood risk reduction, Zimmer Dd No I stands as a testament to the ongoing commitment to water resource management in Kansas.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
