I was recently looking at old bookmarks and thought I'd give the link to wildtroutstreams.com a try.
The website is up and running! I don't know how long it's been back up, or how long it was down, but it's working today, and with an updated format to what I saw the last time I visited. There are now interactive online maps, so you can view the data without downloading, if you so choose.
And wherever the river goes, every living creature that swarms will live, and there will be very many fish. Ezekiel 47:9
