Holloway Lake dam
Holloway Lake
Holloway Lake in Gregg, Texas is a privately owned irrigation reservoir completed in 1959 with a storage capacity of 180 acre-feet. The dam is an earth structure with a height of 18 feet and a length of 750 feet, serving primarily for agricultural purposes. Located on the TR-Little Cypress Bayou, this reservoir plays a crucial role in providing water for irrigation in the region.
Despite its relatively small size, Holloway Lake has a high hazard potential and is classified as having a risk level of 2, indicating the need for careful monitoring and maintenance. While the dam has not been rated for its condition, it is important for water resource and climate enthusiasts to stay informed about the ongoing management and risk assessment measures in place for this structure. With no spillway and limited discharge capacity, the reservoir's ability to handle extreme weather events and potential flood risks is a critical concern for the surrounding area.
With no federal oversight or funding, Holloway Lake is solely regulated and inspected by the state of Texas. While it may not be as well-known as larger reservoirs, its significance in providing essential water resources for irrigation underscores the importance of maintaining its structural integrity and ensuring proper risk management strategies are in place. Water resource and climate enthusiasts should pay attention to developments surrounding this reservoir to understand the challenges and opportunities it presents for sustainable water management in the region.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Holloway Lake
Where does the data for Holloway Lake come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Not Available hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
