How Land-Use and Geology Affect Mountain Streams, with Dr. Nelson Ham - a podcast by Tom Rosenbauer, The Orvis Company

I've long been fascinated by the way geology affects the character and richness of a trout stream, and I know other anglers are as well. My interview this week is with geology professor Dr. Nelson Ham [40:36], who has been studying the effects of both geology and historical land use practices on the character of our trout rivers. The discussion also goes into the value of ground water on how productive our rivers can be. I learned a lot in this interview and I know you will as well.

In the Fly Box this week, we have some interesting an unusual questions and comments, including:

I have six Helios 3 rods and want to sell one. Which one should I sell?

Do you think the affect of COVID on swelling the ranks of fly fishers will go down?

I found an Orvis 1856 bamboo fly rod in the attic of my new house. Was it really built in 1856?

A listener encourages me to keep making fun of various kinds of fly-fishing methods.

In places I used to catch brook trout I am now only catching chubs. Do you think trout will re-inhabit these streams?

A listener reminds me that organizations like Project Healing Waters promote the therapeutic value of fly fishing in young veterans.

Do you think tube flies would be effective for golden dorado?

If it's legal, how many flies do you think are too many on a single leader?

When I fish a dry dropper, why do the smaller fish take my small Zebra Midge and the larger trout take a poke at my dry fly?

What flies and gear are recommended for catching Atlantic mackerel on a fly?

If I don't want to use head cement, is a double whip finish a good way to increase the durability of my flies?

When I use a throat pump on trout, why do my samples sometimes come up empty?
