Tshimikain Creek : Electro Fishing for Rainbow trout.

The Tshimikain was a small with various non-native and native species. The counts of Rainbow were high according to Program Manager Casey Flannigan.d Casey was a part of my crew and we had fun netting Rainbows, Brown Trout, Sculpin, suckers and pike minnow. Crew leader Nick (BUB) had us in waders as we trekked through between ¼ and ¾ of a meandering, up to 4 ½ feet deep running water.

The rainbows were analyzed for weight, length, genetics, and were PIT Tagged above 60 Millimeters. Casey was very insightful I got a chance to talk with her a bunch. Casey was working on her masters degree through Eastern Washington University and her research was on Redband Trout physiology; a nightmare of a thesis that required hours upon hours upon hours of monotonous lab work. Sheesh, basically it was an experiment that analyzed differences in size and change in size under certain conditions of Redband,,,,I can laugh and only imagine the extremely tough variables to analyze, not to mention the statistics involved.! I took away good information about the redband and the adaptations that take place during smoltification. Smoltification does not occur in all redband! I thought it very interesting that only a certain population turn anadromous and become steelhead. Apparently Scientists are still questioning what happens and/or does not happen to redband that allows or disallows certain fish to become steelhead. Also very interesting is the physiology of redband allows multiple spawning over a six year life cycle. Spawning itself can completely drain a steelhead or fish so much so that it can easily cause mortality in many other species of fish; and it does. The redband is a tough tough species and I have a new respect for them from talking with Casey; she also mentioned that the physiology and strength of the steelheads also allows the fish to survive very cold waters and very warm waters that kill many other aquatic biota. I walk away with new knowledge as a fisheries science enthusiast.

Day 10 People of the Big River The Spokane Tribal Hatchery is very unique in it was a thought and an action in it origins; the people: Tim Peone and family, along with a few selected elders decided to create a Salmon Recovery and aquatic biota restoration hatchery on their homelands where they fished and ran and played as children. Vision became reality.         Actions towards Salmon Recovery is very heartfelt among the Spokane. In my experience here at the Spokane Reservation in the past and in the present, I have more or less acknowledged and accepted the fact that the salmon have no longer ran the Spokane River. It was only after I listened to my new friend Warren Seyler that I have a brand new prayer lined up for all the people of the Spokane Reservation and Warrens Mission as an advocate for the passing of sacred History of the Spokane Elders. I am on a similar path and it gives me comfort to know that there are people like Warren that I can reference

Day 8 People Of the Big River2017 Class Sunday July 16 th 2017 Arrival at the Wellpinit reservation powwow and stick game sheds was great; By absolute coincidence I met the local and famous artist Rick Sherwood, Rick had run out of gas and was curious about who Us Natives camping; It turns out he had done the colorful artwork placed sporatically around the grounds above the doorways and such. I got a good feeling from his welcome. It was good medicine to introduce myself to this area in a good way. I would like to highlight a few things that are cool and essential to my health and academic career while here at Wellpinit. First, I think it was great that the Compass treasure hunt (Geocaching 202) was hosted by Pedro; I think use of the compass should be practiced a lot more and Pedro was good about explaining the many different uses of the compass and kept it simple and interesting.
