BULLETIN OF THE UNITED STATES FISH COMMISSION. 
It is said tliat redfish run only for a short time, that they disappear as suddenly 
as they come, and few are seen in any part of the lakes after the run is over. Almost 
every person with whom we conversed on the subject expressed the opinion that the 
redfish, or “grayling,” as they are commonly called, annually come in from the ocean; 
but some believe that they never leave the lake, but retire into the deep parts of the 
lake as soon as the spawning season is over. Positive knowledge on the subject is 
lacking. The few specimens taken in Lake Washington would hardly warrant an 
opinion to be formed as to their habits in these lakes. It would be necessary to observe 
a considerable number from the time they first appear until they leave. 
Surface material . — Collecting with surface tow net was carried on at different 
intervals. As was the case on Lake Washington, surface life was found most abun- 
dant in the evening; at other times a trial of 15 dr 20 minutes would result in a small 
quantity of material. 
Depth of water, temperature, and character of bottom of Lake Sammamish . 
a About 20 feet from bridge; first line sounding. d Commencement of fourth line of soundings. 
b Second line of soundings 250 feet from sawmill. e Soundings close to a brook. 
c Commencement of third line of soundings. /Sixth line of soundings 20 feet from shore.
