Yeah.

We...

And besides huge amount of sleep deprivation that we would do, we would sample our way from Lee's Ferry down through Marble Canyon, and then throw our chub hats on and start, uh, catching not only trout, but chub, to get an understanding of their abundance and vital rates.

Uh, and that program, uh- Lasted all the way to about 2015.

And we learned an inordinate amount based on that study and a concurrent study going on in the middle of the summer, kinda, uh, just right at the cusp of the monsoons happening.

Matter of fact, Tanner Carruthers was one of the techs on that study, uh, and it was run by Charles Ukulik and Maria Jewell.

And, uh, they were just like we were doing, uh, in the main stem, uh, catching young juvenile chub and marking them with these visual implant elastomer tags that I talked about last time that would give us an idea of their size and their location.

Right.

Steve Carruthers and Mike Yard.

at that point in time where the Glen Canyon Environmental Study had provided a lot of information to the entities that were developing the environmental impact statement.

And it had finalized in 95.

And a record decision had come out then in 96 with an experimental flow and Bruce Babbitt signed the thing and that terminated the technical studies of Glen Ken environmental study and the.

The direction of GCS was trying to have an understanding of flows and what those effects were on the natural resources and physical and cultural resources.

As part of the record of decision, they had decided that they would start a program that was called the Grand Canyon Monitoring and Research Center.

And it was to better understand through monitoring and sometimes through research how to protect those resources.

a big window in between

Mm-hmm.

It fell off, very similar to the Carothers Brown book on distribution of rainbow trout as a function of distance, so it decays.

Um, it was hit and miss on other species.

They used trammel nets specifically where they could put them out in large eddies, and they were quite effective But the problem with fishing in phase one was it was unidirectional.

We put in at Lee's Ferry, just like any recreational trip, and we took out either at Diamond Creek or the f- you know, Pierces.

Uh, there wasn't much repeat sampling.

We had a little run about, Boston Whaler or our Zodiac, but we never expanded on the possibility of going further upstream or downstream and coming back to camp.

So e- explain that.
