Buck Run is a beautiful stream, absolutely pristine within the Sadsbury Preserve. The PFBC opened up the section of the stream that runs along Old Mill Road, and that stretch is much more fitting temporary habitat for the put and take, stocked browns and rainbows the commission dumps than the section surrounding Bert Reel Park. That section is treated burtally by bait fishermen an is pretty depleted after opening day. Deeper within the preserve, there is a very diverse mix of spring-creek fish: log perch, 5 or 6 shiner species, a variety of dace, darters, etc. There also seem to be a number of juvenile brook and brown trout in this area. However, these sections of Buck Run are lined with nettles, brambles, etc. an these little wild fish are probably better off left alone. I am going to avoid pin pointing their specific location because I believe these little fish could be very quickly and tragically wiped out by one or two determined individuals. The section of Buck Run that joins with Doe Run in the vicinity of the Laurels preserve is much warmer and broader that the Sadsbury woods section. There are some stunningly large smallmouth in this area. I would say this stream probably has a smallmouth density (relative to its size) that exceeds the lower Brandywine! However - the Laurels has pretty restrictive hours and you must obtain a permit from the Brandywine Conservency to fish there. Laurels staff patrol the stream every day and are serious about the permit issue. Finally -- I have heard that there are some wild brookies in this section. In 10 years of exploring the Laurels, I have never seen any. However, there is certainly a small, but self-sustaining wild brown trout population in this area. I hope that helps!
