Summary
This earth dam stands at a height of 25 feet with a structural height of 32 feet, serving the primary purpose of flood risk reduction along the Lost Creek-TR. With a storage capacity of 469 acre-feet, this dam plays a crucial role in managing the water resources of the region, covering a surface area of 51 acres and draining an area of 1.55 square miles.
Owned and regulated by the local government, Dd No D-1 is inspected, permitted, and enforced by the Kansas Department of Agriculture to ensure its structural integrity and functionality. Despite being rated as having low hazard potential and not yet assessed for condition, this dam's importance in flood risk reduction cannot be understated for the community of LINCOLN and beyond. As an enthusiast of water resources and climate, understanding the details and significance of Dd No D-1 provides valuable insight into how infrastructure like dams plays a crucial role in mitigating natural disasters and ensuring water security in the region.
As part of the Kansas City District, this dam's presence underscores the collaborative effort between federal and state agencies, as well as the involvement of the Natural Resources Conservation Service in its design. With a maximum discharge capacity of 5000 cubic feet per second and a spillway width of 160 feet, Dd No D-1 is a key component in the local water management system. Its historical relevance and ongoing role in flood control and water resource management make it a notable feature for water resource and climate enthusiasts to study and appreciate in the context of sustainable infrastructure development.

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.
