Summary
Constructed in 1978 by the USDA NRCS, this earth dam serves multiple purposes including fire protection, stock watering, and small fish pond management. With a height of 25 feet and a storage capacity of 154 acre-feet, the dam plays a crucial role in flood risk reduction for the surrounding area.
Situated on TR-Welsh Creek, this dam covers a drainage area of 0.28 square miles and has a surface area of 6.3 acres. Despite its low hazard potential, the dam poses a moderate risk, prompting the need for ongoing risk management measures. While the condition of the dam has not been rated, regular state inspections ensure its structural integrity and functionality. With a variety of purposes and a history of successful operation, Dane Ridge Watershed Site D-13 stands as a significant asset in water resource management and climate resilience efforts in the region.
Managed by the Natural Resources Conservation Service and situated in the Rock Island District, this dam is a testament to effective collaboration between local and state agencies in safeguarding water resources. With its strategic location and multiple benefits, including flood risk reduction and fire protection, Dane Ridge Watershed Site D-13 serves as a critical infrastructure for sustainable water management in the area.

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.
