You're going to. Yeah, I started prospecting for trout with a chapter on rich streams versus poor streams one of the

first chapters because you can tell a lot about a river from standing way

back we're here on the west branch of the

Austin in New York State and you can tell a lot about where the fish are going to be

what they're going to eat just by stepping back and looking at the place.

You'll see a lot of round boulders.

They're mostly granite.

So you're not getting a lot of nutrients from the rocks.

The geology determines the character of a river.

And these rocks are mostly granite, as opposed to something like limestone or marble,

where you get some nutrients coming into the river.

So also look at the color of the water.

The color of this water is always kind of tea colored.

And tea colored water typically means water that's not as fertile as water that's

crystal clear. Water also with a light milky tinge is generally limestone water and that indicates a very, very

rich ecosystem. But here we've got tea-colored water and if you look at the rocks, the rocks are kind of contrary to what you might think looking

at the geology and looking at the color of water.

Because the rocks have a fair amount of algae and diatoms and slippery stuff on them.

So you've got some of the characteristics here of an infertile river, but you've also

got indications that it's relatively fertile.

So you've got kind of a balance between the two,

and I would expect you could say this river is kind of in between a Spring Creek or a limestone
