Its not my favorite park by any means...basically a channelized ditch IMO..same can be said about Bennett, or Roaring River.
I have a feeling that dam removal would greatly reduce the amount of water that gets retained in the spring branch and I'm not sure that that would be a good thing. Meramec is set up for mass recreation and bait fishing at the present time....and thats fine with me... Figure it keeps most of the folks who want eat fish in the parks and off the waters that I like to fish.
FWIW, MDC surveyed the habitat between 8 and Scotts when they developed the trout plan several years ago and I had a chat with one of the biologists about it....They considered the habitat between the Spring and Suicide Hill to be suitable for blue ribbon management, but they figured that blue ribbon management would be hard to implement on the entire stretch. 8 to Scott's is a unique piece of water. Decent bass water from 8 to the spring, Blue Ribbon quality trout habitat from the spring to Suicide, and marginal trout & bass habitat from Suicide down to Scott's. Its a long stretch, with only 3 miles of good trout habitat, so I think red ribbon is about the best we can hope for...
Its a tough place to fish thats for sure. Its different from most of our other trout waters because the bottom is mostly fine gravel and there are only a few hard points in the stream...The food base is made of tiny stuff because the gravel is too small to grow lots of big bugs, crayfish, or sculpins. There are plenty of minnows though....I've caught plenty of nice browns and rainbows down there over the years but you really have to be on your game and work for them. Fish early or late, camp on the river, hike up or down in the dark. Cheers.
