Tables 1 to 5 give the aggregate Washington and Oregon catches for 1938, by species,
weeks, and zones. These figures include only those catches that were reported by
locality and date. There is a relatively small portion of the total catch that is reported
without these important data and these have been excluded from this analysis, although
for completeness they are given in table 6. The catch of chinook and silver salmon
made in the ocean outside the mouth of the river by troll fishermen was not given in
the original report by the board of consultants, but is included here. Occasionally
deliveries are reported during the spring season as of Sunday. Since the period from
6 p. m. Saturday to 6 p. m. Sunday is closed to fishing each week during the spring
season, such catches have been added to those of the preceding week. Catches made
on Saturday are not infrequently held over and delivered on Sunday, and it rarely
happens that catches are made after 6 p.m. on Sunday and delivered that same evening.
The zones correspond to the Washington counties bordering the river, beginning
at the mouth. Zone 1 is that part of the river that is bounded on the north by Pacific
County, Zone 2 by Wahkiakum County, Zone 3 by Cowlitz County, Zone 4 by Clark
County, Zone 5 by Skamania County, and Zone 6 by Klickitat County. The catch
in Zone 5 has, on the advice of both the Washington and Oregon officials, been referred
wholly to the area below Bonneville Dam. This zone extends above Bonneville for
some distance, but for a part of this distance the river is closed to all fishing and the
catch in the remaining portion is so small as to be negligible, either when omitted from
the record of the catch above or added to the record of that below Bonneville.
In this analysis we have necessarily omitted consideration of three elements in the
catch which are recognized as important but which cannot, with the data at hand, be
evaluated. These are: (1) The catch in the ocean by the troll fishery; (2) the hookand-lme
catch by sport fishermen; and (3) the catch made by Indians for their own use,
especially at Celilo Falls.
The troll fishery is very important, and from southeastern Alaska to the mouth of
the Columbia it draws largely upon the supply of Columbia River chinooks—as demonstrated
by tagging experiments (Pritchard 1934, Fisheries Service Bulletin, Jan. 3,
