Springer Run Estimate

I did a little noodling in Excel on the run size. According to the Compact documents, actions are based on an estimated run size of 145,000 fish over Bonneville.
Based on my calculations, we're on track for a run size of about 188,000 fish. To reach this, I used the following bonneville dam counts. 4/12 and before are actual. 4/13 and after are an average of the previous week, and then declining as shown.
This estimate is probably conservative, as we have had a couple of huge days over the dam in the past two years, and that isn't factored in.
What this means is that if the run size is larger, we may get allowed to handle more wild fish, and that means the season my get continued. We were on track to hit the allowable impact by yesterday, based on the original run size.
So, the biologists are probably running similar, but more educated spreadsheets. Seems to me like we'll likely be able to continue fishing. The bad news is, the commercials may get a day in there as well that could hurt us.
BTW, dates are off by one, bad typing. Doesn't effect the basic conclusion.

What kind of curve did you assume? Most statistical type curves use some form of a Gaussian distribution (ie, Bell curve). This type of curve rises and falls much more rapidly than what you have tabulated.

yes but his numbers on the rise are actual #s

I didn't assume a curve at all. I just eyeballed the rise and fall in the past two years, and did some very casual estimating. Took about 5 minutes, so that's all it's worth. But it was enough to make me make plans to fish this coming week - that we might have a season.

You were starting the process of making your own curve, which is fun to do (at least it was for me). Once the curve seems to peak, you should have about the same numbers on the downward side.

Spawnout,
I agree. The season extension will be based on the handling of wild fish, in combination with the projected run size. My understanding is that either statistic can effect the decision, and the point of the above is that it seems pretty straighforward to conclude that the run size estimate should be adjusted upward. I hope they do, and I guess we'll know tomorrow.

I heard it again today, second hand from a bioligist that they where not going to open it... you cant beleive how this ticks me off....its such a good fishery for me becouse i can take people out and relax and catch springers, my other fisheries are elbow to elbow and more or less combat fishing, which nobody really enjoys but ya gotta do if your going to barba cue springers this summer....I think I am going to take one for the team and just go fish, screw em....

SH, If you would simply calculate the standard deviation for the last 2 years using dates, capture out to 2SD, and then project inside that curve for this year, you could probably tighten up your model. You do recall how to do that from Econ/Stats, don't you?
