Summary
The dam, standing at a height of 14 feet, has a storage capacity of 979 acre-feet and serves as a vital water resource for the surrounding area. Situated on Boggy Creek, the dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its structural integrity and safety.
Despite its modest size, Simms Lake Dam poses a high risk (2) according to a risk assessment, highlighting the importance of proper maintenance and management measures. The dam does not have a spillway and features buttress core types with an earth foundation. While the dam does not have associated structures or locks, it is equipped with one outlet gate for water release. As a significant component of the local water infrastructure, the dam plays a crucial role in providing water for irrigation, recreation, and emergency purposes in the region.
Water resource and climate enthusiasts can appreciate the significance of Simms Lake Dam as a key feature in the water management system of Leon County, Texas. Its construction in the late 1970s reflects the importance of maintaining and regulating dam structures to ensure water security and safety for the surrounding community. With its high risk designation, ongoing monitoring and assessment of the dam are essential to prevent potential hazards and maintain its functionality for both current and future generations.

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.
