Back in the 90s when I was with TWRA we found that brook trout were often outcompeting rainbows in some streams and were gaining ground so to speak. Other streams showed brook trout losing some ground to rainbows, but not much. There was an overall net gain in miles of brook trout streams over the course of the 90s from what we found. This did not include the Left Fork of Hampton Creek restoration and similar. My best guess as to why the brookies seem to be doing better in competing with rainbows has to do with forest succession. I think the forest canopy and the streams themselves have returned to conditions similar to the pre-logging era. There are so many possible variables that could affect population dynamics though we may never know.
