These eggs appeared to be in the "tender stage" and died soon after handling. On December 7 all of the marked nests except two were exposed. Sample eggs were removed and were found to be developing normally. At this time tl ggs were buried under from four to seven inches of gravel. The water level of the Lake was K) inches below the surface of the nests. Even though the surface was dry, the eggs buried only four inches were kept moisl by capillary water. The temperature of the sand in whieh the eggs were embedded was degrees F. The surface of the lake was 47 degrees and the seepage areas lv degrees F.' On December 12 the top three inches of the nests were frozen. Below this level the sand was not fro/en and the eggs were continuing development at •'!!• degrees F. The eggs in the seepage areas were still in 48 degrees P. water and several appeared to be in the firsl stages of "; The temperature of the lake was degrees F.

Three dead kokanee were also seen. At least six nests were noted in the firsl hundred yards of stream below the dam. and there were probably more These kokanee appeared to be larger than those in the lake and were estimated to be from 18 to 20 inches long, with a1 leasl one individual about 24 inches in length.
