Summary

Completed in 1970, this dam has a primary purpose of recreation and stands at a height of 17 feet, with a storage capacity of 73 acre-feet. Situated on TR Spring Creek, the dam offers a serene escape for water resource and climate enthusiasts, covering an area of 8 acres and draining a watershed of 120 square miles.

Despite being unregulated by the state and having a low hazard potential, Mononame 772 provides a valuable recreational space for the local community. With its buttress core type and unknown foundation, this dam has not been rated for its condition assessment. While it may not be a prominent feature in terms of size or capacity, this dam serves as a reminder of the diverse ways in which water resources can be utilized and appreciated in different regions.

As a site that has not undergone recent inspections or assessments, Mononame 772 presents an opportunity for further study and evaluation in the realm of water resource management. Its location in the Memphis District underlines its significance within the broader context of dam infrastructure in the region. For water resource and climate enthusiasts, this dam offers a glimpse into the intersection of human engineering and natural landscapes, showcasing the potential for sustainable recreation and conservation efforts in Missouri.

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.
