Summary

This dam, completed in 1974, serves multiple purposes including fire protection, stock, and small fish pond management. With a dam height of 21 feet and a storage capacity of 70 acre-feet, it is regulated by the IOWA DNR and falls under the jurisdiction of the state with permitting, inspection, and enforcement in place.

Situated on the TR-PINE CREEK river or stream, Iowa Noname78 is a vital resource for water management in the area. The dam's low hazard potential and moderate risk assessment make it an important structure for the community. Managed and designed by USDA NRCS and funded by the Natural Resources Conservation Service, this earth-type dam plays a crucial role in ensuring water availability for firefighting, livestock, and fishery activities in the region.

Despite being in operation for several decades, the condition assessment of Iowa Noname78 is currently not rated. However, with state-regulated inspections and enforcement in place, the dam continues to serve its purpose effectively. As a key component of the local water resource infrastructure, Iowa Noname78 stands as a testament to sustainable water management practices and climate resilience efforts in the state of Iowa.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
