Summary
Completed in 1953, this private-owned earth dam stands at a height of 23 feet, with a length of 728 feet, and a storage capacity of 240 acre-feet. Its primary purpose is for recreation, offering a serene retreat for water resource and climate enthusiasts alike.
While the dam lacks a spillway, it features an outlet gate to regulate water levels, providing a safe and enjoyable environment for visitors. The dam's location along North Plum Creek adds to its allure, nestled within the picturesque Texas landscape. Despite its high hazard potential, the dam's condition remains unrated, prompting a need for further assessment and risk management measures.
As water resource and climate conservationists continue to appreciate the Weymouth Ranch Lower Lake Dam for its recreational value, there is a growing concern for its safety and sustainability. With a risk assessment rating of "High (2)" and limited information on emergency preparedness, there is a call for increased scrutiny and proactive measures to ensure the dam's longevity and the protection of its surrounding ecosystem.

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.
