Summary
Constructed in 1998, this Earth dam serves as a Fish and Wildlife Pond on the Baskett Slough stream. With a height of 9 feet and a length of 1620 feet, the dam has a normal storage capacity of 87 acre-feet and a maximum storage of 287 acre-feet, covering a surface area of 58.3 acres. The dam plays a crucial role in habitat conservation and water management for the region.
Despite its low hazard potential, Taverner Marsh Dam is rated as in poor condition as of the last inspection in 2017. The dam features stone core types on an unlisted/unknown foundation and is equipped with other controlled outlet gates. The Federal agency responsible for its design, construction, regulation, inspections, and operations is the Fish and Wildlife Service. With a primary purpose of serving as a habitat for fish and wildlife, the dam contributes to the environmental sustainability and conservation efforts in the area.
As a key component in the water resource management system, Taverner Marsh Dam provides vital support for the Baskett Slough ecosystem and surrounding areas. While facing maintenance challenges, the dam continues to fulfill its role in enhancing biodiversity and preserving the natural habitat. Climate enthusiasts and water resource advocates can appreciate the significance of this Federal-owned structure in safeguarding the ecological balance and promoting sustainable practices in Oregon.

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.
