. California fish and game. Fisheries -- California; Game and game-birds -- California; Fishes -- California; Animal Population Groups; Pêches; Gibier; Poissons. â 2, I l Mil"!.". I \ FISH AND <. A WE One of the besl areas Eor observing the spawning of kokanee in Donner Lake is located off the end of Waggoner's boat pier on the north shore. This area is only a fev hundred feel from the highway and is easilj accessible even through the heaviesl of snow. The shore at this poinl slopes gently for aboul 1"" feel and then drops off abruptly to depths of 30 i" 50 feet. When the lake Level is normal, the edge of the shelf is tinder aboul six to eighl feel of water. The water is one to three r this poinl when the kokanee begin to spawn and the water surface is aboul one to one and a half feel below it at the point of maxi- mum drawdown. The section where the observations were made is about 100 yards long and is composed of a mixture of sand, "-ravel, and cobbles on a clay substrate. About one quarter of this lies in a spring seepage area. Since the clay base is tipped slightly toward the lake, the gravel in the seepage area lias a slow but constant flow of water through it. Tic first kokanee were seen on the fourth of November, 194M. when the water temperature was 51 degrees 1-'. at the surface. These consisted primarily of males and much fighting and splashing was noted. On the fifth of November a gill net was set in water from depths of six to fifty feet. When this net was picked up on November 6, eight male and one female kokanee were taken. All were in water shallower than 20 feet except the female, which was taken at 50 feet. The males had free flowing milt and the female emitted eggs on compression. The average size of all fish taken at this time was 18^ inches and the average weight was about two pounds. The coloration and body conformation were identical with those described for the anadromous form of the red salmon Kiuure 109).
