On the off chance that this is useful to anyone else. Here's
the code I came up with to set the erc-hide-list variable for a
specific channel:

; Set the global variable to hide the list of message types
(setq erc-hide-list '("JOIN" "PART" "QUIT" "MODE" "NICK"))

(add-hook 'erc-join-hook
          (lambda ()
            (if (equal "#MyIRCChannel" (buffer-name))
                (set (make-local-variable 'erc-hide-list) '()))))

Thanks Edward for pointing me in the right direction. It's amazing how
extensible and well thought out Emacs is.
