Whitesail Lake Map-Area The ultimate plan to bring the whole Kitimat scheme to full capacity of 1,695,000 horsepower (Wolcott, 1954, p. 1385) requires the construction of a second tunnel from Tahtsa Lake to Kemano, the construction of a dam at the outlet of Kidprice Lake and a tunnel between Nanika and Tahtsa Lakes. The Nanika-Kidprice drainage will then flow into Tahtsa Lake and augment the storage in the basin. The powerhouse at Kemano will have to be extended and additional generating equipment installed. The engineering and geo- logical experience and information gained in the construction of the first tunnel will be of advantage in the construction of the second. Geological conditions between Nanika Lake and Tahtsa Lake are similar to those encountered in the tunnel between Tahtsa and Kemano, therefore, records kept on the first phase of the project should be very useful in the construction of the later phase.
