Summary
Managed by the Natural Resources Conservation Service, this earth dam structure stands at 25 feet high with a hydraulic height of 13 feet. The reservoir has a storage capacity of 33.5 acre-feet and is regulated by the Oregon Water Resources Department, ensuring state jurisdiction, permitting, inspections, and enforcement are in place for its operation.
With a low hazard potential and a moderate risk assessment rating, Rickman Reservoir serves as a vital resource for water management in the region. The reservoir features an uncontrolled spillway and slide gates for outlet control, contributing to its efficient irrigation functions. Although the dam's condition is currently not rated, its last inspection in May 2013 indicated a satisfactory status. While the reservoir does not have inundation maps or an emergency action plan in place, its strategic location and operational measures demonstrate a commitment to responsible water resource management.
Enthusiasts of water resources and climate will find Rickman Reservoir to be an intriguing case study in private water infrastructure. Its location, design, and purpose offer insights into sustainable water management practices in arid regions like Oregon. As climate change continues to impact water availability, reservoirs like Rickman play a crucial role in supporting agricultural activities and ensuring water security for local communities. Further research and monitoring of Rickman Reservoir can provide valuable lessons for sustainable water resource management in the face of evolving climate challenges.

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.
