Summary
This private-owned earth dam stands at 19 feet high and stretches 895 feet in length, with a storage capacity of 122 acre-feet. Despite being primarily used for irrigation purposes, the dam does not have a spillway and is not regulated by the state.
The dam's hazard potential is rated as high, signaling the importance of proper risk management measures. Although the condition assessment is not rated, the dam has not been inspected recently, highlighting the need for regular evaluation and maintenance. Furthermore, the dam lacks an Emergency Action Plan (EAP), indicating a potential gap in emergency preparedness.
Lake Donna V Dam's association with the Rocky Creek and its strategic location in the Galveston District make it a significant water resource within the region. While it continues to support irrigation needs, the dam's risk assessment and maintenance status underscore the importance of ongoing monitoring and potential improvements to ensure the safety and efficiency of its operations.

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.
