I did go to the meeting and I really enjoyed it. What they did basically was a huge survey of the lake along what is known as the (?) zone... sorry, it is an area from the shoreline out to about 15 ft. in water depth. They covered 40% of the entire lake shoreline, to include Mercer Island shoreline. Normally they cover about 10-15% of a lake. They sampled 41,000 fish over about 4-5 days. They did a comprehensive look at all the fish obtained, to include size measurements, weight measurement, aged determination, and a whole bunch of other stuff.
They sampled by means of electroshock, gill netting, and fyke netting.
At least one point to consider is that they can only sample within this "Shelf" 15' water colum, and therefor you have to realize that there would be assumably larger fish of certain species that weren't able to be sampled, i.e. the larger Cutthroats, and other silver types that spend more time out in the open water area of the lake.
Anyway, ( I probably shouldn't started this posting until I have the time to input the data) I have to run out, but I will post again with most of the data. It was really fascinating to see that they found representation of about 23 different species of fish. Some really weird stuff too.
