Summary
Designed by the USDA NRCS, this earth dam stands at a height of 24 feet and has a hydraulic height of 22 feet. With a storage capacity of 121.1 acre-feet, the dam serves to control the flow of the TR-Little Wyaconda River and covers a surface area of 3 acres.
Despite its relatively low hazard potential, Schmitz Dam poses a moderate risk, according to the latest assessment. The dam features an uncontrolled spillway and outlet gates, with a maximum discharge capacity of 31 cubic feet per second. While it has not been inspected since its completion in 2004, the structure's condition is currently not rated. The dam is not under state regulation, permitting, inspection, or enforcement, and is privately owned.
Water resource and climate enthusiasts interested in Schmitz Dam can appreciate its role in managing water flow and preventing erosion along the TR-Little Wyaconda River. With its low hazard potential and moderate risk assessment, the dam presents an opportunity for further monitoring and maintenance to ensure its continued effectiveness in grade stabilization. As a privately owned structure, the responsibility for its upkeep falls on the owner, highlighting the importance of private-public partnerships in managing water resources for the benefit of local communities and ecosystems.

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.
