Montgomery Lake Dam Reservoir Report
Last Updated: March 14, 2026
Montgomery Lake Dam, located in Presidio, Texas, is a private Earth dam primarily used for irrigation purposes along TR-Crystal Creek.
Summary
Standing at a height of 40 feet with a length of 200 feet, the dam has a storage capacity of 206 acre-feet and a maximum discharge of 0. Despite lacking a spillway, it is equipped with one outlet gate for water control. The dam's hazard potential is marked as "Not Available" with a risk assessment of "High (2)", suggesting potential safety concerns.
This dam is not under state jurisdiction or regulation, but it is subject to state permitting and inspection. While the original designer remains unknown, the structure's core type is listed as Buttress with an unspecified foundation type. With its location in a picturesque area and its vital role in providing irrigation water, Montgomery Lake Dam serves as a key component in the water resource management of the region. Enthusiasts of water resources and climate will find the unique characteristics and potential risks associated with this dam intriguing and worthy of further exploration and study.

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.
