Summary
This earth dam, with a height of 17.5 feet and a hydraulic height of 24 feet, was designed by the USDA NRCS for the primary purpose of flood risk reduction. With a storage capacity of 86 acre-feet and a drainage area of 0.49 square miles, this dam plays a crucial role in managing water flow in the region.
Despite its low hazard potential and satisfactory condition assessment, Dd No 101 has not been inspected since March 2011. It has a moderate risk rating and is classified as uncontrolled spillway type with a spillway width of 86 feet. The dam has no outlet gates and is associated with the Dow Creek-TR river or stream. It is owned by the local government and funded by the Natural Resources Conservation Service, highlighting the collaborative effort to protect the community from potential flood risks.
While Dd No 101 serves its purpose effectively in flood risk reduction, there are concerns regarding the lack of recent inspections and maintenance activities. With its strategic location and significant contribution to water resource management, it is essential for relevant authorities to prioritize regular assessments and necessary upgrades to ensure the continued safety and effectiveness of this vital infrastructure.

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.
