Summary
Designed by USDA NRCS, this dam primarily serves the purpose of debris control with a dam height of 17.5 feet and a length of 450 feet. It has a storage capacity of 51 acre-feet and covers a surface area of 1.6 acres, with a drainage area of 0.62 square miles. The dam features an uncontrolled spillway with a width of 63 feet and is classified as having low hazard potential.
Although Gsd No 17 (Pederson) is not currently rated for its condition, it is considered to have moderate risk with a rating of 3 out of 5. The dam does not have any outlet gates or associated structures, and it has not been inspected or assessed for emergency preparedness measures. Despite its low hazard potential, it is important for local authorities to regularly monitor and maintain this dam to ensure its continued safety and functionality, especially in the face of changing climate conditions that may impact water resources in the region.
Located in Brown County, Kansas, Gsd No 17 (Pederson) stands as a crucial infrastructure for managing water resources in the area, particularly in controlling debris and maintaining the integrity of Grasshopper Creek. As climate enthusiasts and water resource stakeholders, it is vital to stay informed about the condition and risk assessment of dams like Gsd No 17 (Pederson) to promote sustainable and resilient water management practices in the face of a changing climate.

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.
