Summary
Built in 1977, this private-owned Earth dam serves primarily for grade stabilization purposes, with a hydraulic height of 29 feet and a structural height of 31 feet. Its low hazard potential and moderate risk assessment make it a crucial asset in managing water resources and mitigating potential climate-related risks in the region.
With a storage capacity of 36 acre-feet and a drainage area of 377.6 square miles, the G.Talmage Structure Dam plays a pivotal role in maintaining the water levels and flow rates in the surrounding area. Despite being uncontrolled, the spillway of the dam boasts a width of 12 feet, ensuring efficient water discharge during peak flow periods. The dam's design, incorporating Stone core and Soil foundation, showcases a balanced approach to structural integrity and sustainability in water management practices.
As a part of the Kansas City District, the G.Talmage Structure Dam contributes significantly to the overall water infrastructure in Nodaway County, Missouri. Its strategic location and design reflect a commitment to environmental stewardship and community resilience in the face of changing climate patterns. For water resource and climate enthusiasts, this dam stands as a testament to the importance of proactive infrastructure development in safeguarding our natural resources for future generations.

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.
