Summary
This earth dam, designed by the USDA NRCS, serves the primary purpose of debris control along Grasshopper Creek. With a height of 23 feet and a hydraulic height of 19 feet, this dam spans 600 feet in length and has a storage capacity of 79 acre-feet. Despite its relatively low hazard potential, the dam is categorized as having a moderate risk level, indicating the need for ongoing risk management measures.
This structure, situated in Brown County, Kansas, plays a crucial role in regulating water flow in the area and protecting against debris buildup. While not currently regulated or inspected by state authorities, Lowe-Johannes Gsd No 79 serves as a key component of the local water resource infrastructure. With a spillway width of 80 feet and an uncontrolled spillway type, the dam is designed to manage excess water flow during periods of heavy rain, contributing to the overall flood control efforts in the region.
Although the condition assessment of Lowe-Johannes Gsd No 79 is currently listed as "Not Rated," the dam's operational status and risk level suggest the need for ongoing monitoring and maintenance. As climate change continues to impact water resources and weather patterns, structures like this play a crucial role in mitigating flood risks and ensuring the safety of nearby communities. With a focus on debris control and water flow regulation, this dam exemplifies the intersection of water resource management and climate resilience in the face of evolving environmental challenges.

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.
