Lake Tacoma has a maximum depth of 256 feet (78 meters). This significant depth makes it a notable body of water, contributing to its overall characteristics and the surrounding ecosystem.
Understanding Lake Tacoma's Dimensions
Beyond its impressive depth, Lake Tacoma possesses several other key dimensions that define its size and hydrological properties. These measurements provide a comprehensive overview of the lake's physical characteristics.
Key Characteristics of Lake Tacoma
To provide a clearer picture of Lake Tacoma, here are some of its primary features:
| Characteristic | Measurement |
|---|---|
| Max. Depth | 256 feet (78 m) |
| Max. Width | 18 miles (29 km) |
| Surface Elevation | 350 meters (1,150 ft) |
| Residence Time | Approximately 200 years |
What These Dimensions Mean
- Maximum Depth: At 256 feet (78 meters), Lake Tacoma's depth is a crucial factor influencing its thermal stratification, water volume, and the types of aquatic habitats it supports. Deeper lakes often provide more stable environments for diverse species and can maintain consistent water temperatures throughout the year.
- Maximum Width: The lake stretches 18 miles (29 km) across, indicating a substantial surface area. This contributes to its overall water capacity and can influence its potential for various human activities or natural processes.
- Surface Elevation: Located at 350 meters (1,150 ft) above sea level, Lake Tacoma's elevation places it within a specific geographical and climatic zone. This position can affect its watershed, the sources of its water, and its surrounding environment.
- Residence Time: A residence time of approximately 200 years means it takes about two centuries for the lake's total volume of water to be completely replaced by inflow and outflow. This relatively long period suggests a stable water body that is less susceptible to rapid changes in water quality due to new inputs, though it can be influenced by long-term environmental factors.
Understanding these dimensions provides valuable insight into Lake Tacoma's environmental characteristics and its role within its natural landscape.
