| − | Lake Tahoe has a water clarity of about 100 ft (30 m) deep. Factors contributing to its clarity include the following: | + | Lake Tahoe has a water clarity of about 100 ft (30 m) deep. Factors contributing to (and affecting) its clarity include the following: |
| | + | *Around 40 percent of the precipitation that falls into the Lake Tahoe Basin lands directly on the lake. |
| | + | *The remaining precipitation drains through granitic soils, which are relatively sterile and create a good filtering system. However, development on the south end of the lake near the Truckee River inlet has affected clarity in that portion. |
| | + | *Approximately 85% of the land surrounding Lake Tahoe is protected from development as Nevada or California State land or land under the jurisdiction of the United States National Forest Service. Development is also strictly controlled by the terms of a bi-state compact between California and Nevada. |
| | + | *One major grocery chain in the area (Raley's, which has three locations in cities/villages adjacent to the lake) does not offer plastic bags to customers, only paper or reusable bags are offered. |
