| The
escapement goal on Quillayute River System for wild winter-run steelhead
is 5900 spawners. The table below gives the run, harvest and escapement
goals for the most recent ~20 years for which complete data is available.

| The
graph below shows the escapement and total run size for wild winter
run steelhead. The difference between the escapement and total run
size is the combined sport and tribal harvest. The current up swing
is not unprecedented, as there was a similar up swing in the mid to
late '80s. Most steelhead from a given brood year mature and return
as adults 3-5 years later, with a four year maturation. Additionally,
7-15% of mature fish return the year after spawning as repeat spawners.
It is interesting to note that the current upswing had its initial
genesis in a year when escapement was slightly below goal ('91 vs.
'95). This is also somewhat in evidence in the up swing of the 80's
('84 vs. '88). |

graph below shows additional detail on harvest, escapement and run
size for the last 10 years or so. The total height of the colored
area represents the total run size, with the portions that went to
escapement, tribal harvest and sport harvest shown by different colors.

| The
spawning escapement short-fall of '91 was the result of an expanded
net fishery, that allowed the Quillayute tribe to take their share
of the harvest, the balance of the sport share and dip into the escapement
goal. This is more clearly shown in the bar chart below. |

In this chart,
for each year, separate bars depict the sport harvest and tribal
harvest. The first bar in each year is 50% of the harvestable surplus,
which is the number of fish available to either party, also referred
to as the harvest share (Surplus=total run - escapement goal, Harvest
share = 50% of surplus.) Sport anglers have never taken their share
on this system, even before the restrictions that were enacted during
the mid to late 90's. The tribe has taken more than their share
on occasion, but during the current up swing are harvesting well
below their share. It remains to be seen whether or not they will
shorten their netting schedules when runs return to a more normal
level.
