BULLETIN OF THE UNITED STATES FISH COMMISSION. 
water always becoming gradually shallow toward the other shore. Except after heavy 
or continued rains the water is exti’emely clear, and even after rains it is not turbid 
enough to prevent one seeing to the bottom of the deepest pools. Ordinarily, when 
the surface is not rippled by the wind, one can very easily see even very small fishes 
in any part of the stream where they chance to be; so that one may walk the length 
of the creek and count all the fishes in it over 3 or 4 inches long, and feel pretty 
confident he has seen all there really are, if he but scrutinize the stream carefully. 
Fishes . — One rarely sees a stream with so few fish in it as this. Species and 
individuals are both few. Besides the redfish, which come into the creek only at 
spawning time, the only species of fishes which we saw during a month’s observation 
were the following: 
Bull trout {Salvelinus malma), not more than a dozen. 
Chinook salmon ( Oncorhynclms tschawytscha), a few young, none over 6 inches long. 
Minnow {Leuciscus halteatus), a few seen occasionally. 
Young whitefish and young suckers probably run up into the inlet, and the blob 
may also do so now and then, but we never saw these species there. 
Cut-throat trout should also be found there, but we are not sure that any were 
seen. All the small fish which looked like trout proved upon examination to be young 
Chinook salmon. 
Temperatures recorded at camp on Alturas Lake Inlet, August S9 to September 18, 1895.
