Mm-hmm

... were calibrated, uh, to one to another f- over an 11-year period.

So you've got flow in one related to flow in the other, water quality in one related to water quality in the other, y- the aquatic ecosystem health.

All of those are, are calibrated side by side.

One of the big challenges in forest wa- forest watershed scale research is when there's a disturbance, uh, and you're left comparing undisturbed watersheds to disturbed watersheds, there's a certain amount of assumption you have to put in to saying, "Well, we're gonna assume that the undisturbed watershed or the disturbed watershed would've been similar to the undisturbed watershed." Well, in this particular case, they call that a paired catchment study or a before/after controlled impact study.

Effectively what it is is studying two watersheds, uh, side by side prior to any disturbance, then having a disturbance affect one watershed-

Yeah.

We're still continuing to do the work on the Star Creek logging.
