I might get ripped a new one for even suggesting this, but part of the clutter here is the fact that you have so many interests being packing into one site.
Make a new snowboarding forum, make a new moutaineering forum, spread it out so the boaters get a clean interface, and the boarders get what they want etc... domains for each interest is what I am suggesting.
I am still working on my community design for boarding and one for climbing but my boating community design is pretty good. I know the buzz is much older and more established but you might find idea's on our site that you like or want to incorporate into the buzz.
I am already running a wide array of usgs gauges and local water authorities and the such. If you wanted I could soup up a flows page for the state of CO for you
It is already configured to take different qstrings for searching and stuff so you can do something like just flooding rivers in Oregon.
I could make a nice looking version of that page color schemed just like the buzz so it would function as one unit. I dunno just an offer if you wanted to dig on some of the tools I have built.
