Summary

Designed by USDA NRCS, this site is regulated by the Iowa DNR and serves multiple purposes including fire protection, stock, and small fish pond, as well as flood risk reduction. The earth dam, with a height of 26 feet and length of 496 feet, was completed in 1969 and has a storage capacity of 50 acre-feet, making it a valuable asset for water management in the region.

With a drainage area of 0.17 square miles, Walters Creek Watershed Site 39-1 has a low hazard potential and a moderate risk assessment rating. The dam has not been rated for its condition, but it is regularly inspected by the state regulatory agency and is equipped with an uncontrolled spillway. Despite its small surface area of 2 acres, the site plays a significant role in water conservation and flood control efforts in the area. Overall, Walters Creek Watershed Site 39-1 is an essential infrastructure for maintaining water resources and managing climate-related challenges in the region.

The site's location in Lake Icaria, with a latitude of 41.0828 and longitude of -94.6721, underscores its importance in the local ecosystem. As part of the Kansas City District, the dam is owned by the local government and funded by the Natural Resources Conservation Service. With its strategic placement and design, Walters Creek Watershed Site 39-1 serves as a critical component of the region's water infrastructure, highlighting the intersection of water resource management and climate resilience in the area.

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.
