Summary
This earth-type dam stands at 15 feet in height and stretches 750 feet in length, creating a reservoir with a storage capacity of 120 acre-feet. Situated along TR-Maguey Creek, the dam plays a crucial role in providing water to the surrounding area, contributing to water resource management in the region.
Despite its age, Beckman Lake No 2 Dam has not been rated for its condition, but its hazard potential is labeled as not available. The risk assessment for the dam is considered high, highlighting the importance of ongoing monitoring and maintenance to ensure its structural integrity and safety. With no spillway and limited information on its inspection frequency, there is a need for continued oversight and risk management measures to safeguard the surrounding community and water resources.
As water resource and climate enthusiasts, the Beckman Lake No 2 Dam serves as a focal point for understanding the intersection of infrastructure, water supply, and risk management in the face of changing environmental conditions. With its location in a high-risk area and limited hazard information available, this dam underscores the importance of proactive measures to mitigate potential risks and ensure the resilience of our water infrastructure in the face of a changing climate.

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.
