Failure

So I went to Red Brook in MA today because I've heard and read a lot about there being a great population of sea run brook trout. Well I couldn't find any..... I started at Red Brook Road at Lyman Preserve, but no fish; we didn't even see any. Can anyone tell me why that is because I am slightly disappointed. :( The stream itself  is very pretty and they did a great job restoring it; it looks like a very healthy spring creek but i didn't even see a fish, let alone catch one.
