Lake Tahoe has upward of a hundred feeders, among which may be named Glenbrook, the Upper Truckee, Fallen Leaf Creek, Eagle Creek, Meek's Creek, General Creek, McKinney Creek, Madden Creek, Blackwood Creek, and Ward Creek, all of these being constant streams, pouring many thousands of inches of water daily into the Lake even at the lowest flow, and in the snow-melting and rainy seasons sending down their floods in great abundance.
To many it is a singular fact that Lake Tahoe never freezes over in winter.

This is owing to its great depth, possibly aided by the ruffling and consequent disturbance of its surface by the strong northeasterly winter winds.

The vast body of water, with such tremendous depth, maintains too high a temperature to be affected by surface reductions in temperature.

Experiments show that the temperature in summer on the surface is 68 degrees Fahr.

At 100 feet 55 degrees; at 300 feet 46 degrees; at 1506 feet 39 degrees.
Twenty years ago the thermometer at Lake Tahoe registered 18 degrees F._below zero_, and in 1910 it was 10 degrees F.below.
