Granger Lake has a maximum depth of 50 feet.
This figure represents the deepest point measured within the lake. Like many reservoirs, the actual water level and, consequently, the average depth can fluctuate due to environmental factors and operational management.
Understanding Lake Depth
The maximum depth indicates the deepest spot under normal operating conditions. It's a key characteristic that influences the lake's ecosystem, recreational uses, and management. While 50 feet is the deepest point, vast areas of the lake will be shallower, particularly near shorelines or in upstream sections.
Key Characteristics of Granger Lake
Granger Lake is a significant body of water in Central Texas, serving multiple purposes. Below is a summary of its key facts, including its maximum depth:
| Feature | Detail |
|---|---|
| Maximum Depth | 50 feet (approximately 15.24 meters) |
| Location | Williamson County, Texas, USA |
| Primary Purpose | Flood control, water supply, recreation |
| Managing Agency | U.S. Army Corps of Engineers (USACE) |
Factors Affecting Lake Levels
The depth of Granger Lake is not static. Several factors contribute to its changing water levels:
- Rainfall and Drought: Periods of heavy rainfall can increase the lake's volume and depth, while prolonged droughts can significantly lower water levels.
- Water Releases: As a flood control reservoir, the U.S. Army Corps of Engineers actively manages water releases through the dam to mitigate downstream flooding or to maintain water supply for communities.
- Evaporation: Texas's warm climate leads to considerable water loss through evaporation, especially during the hot summer months.
These fluctuations are a normal part of reservoir management and impact everything from boat ramp accessibility to fish habitats.
Recreational Considerations
The depth of Granger Lake is an important consideration for various recreational activities:
- Boating: Knowledge of depth is crucial for safe navigation, particularly for boats with deeper drafts, to avoid hazards like submerged obstacles or shallow areas during low water periods. Boaters should always be aware of current lake conditions.
- Fishing: Different fish species prefer varying depths. Anglers often adapt their techniques and locations based on where fish are likely to congregate, which can be influenced by water depth, temperature, and structure.
- Swimming: While typically confined to designated swimming areas, understanding the general depth profile of the lake contributes to overall safety for swimmers.
