The use of modern fish planting equipment assured completion of the restocking prop'ram in four days, from November 1 to 4, in which a total of 7n,'200 eastern brook (5 inches long), averaging per ounce, were planted in the lake from Hot Creek State Fish Hatchery.

The day after restocking was begun, the newly planted trout were noticed "working" near the edges of reed beds and marshes in the lake. Repeatedly thereafter, the newly planted trout were noticed all around the lake until December 14, when the lake became icebound for the winter.
