Mac and GB03,
The folks are referring to part of the Native Brook Trout restoration project on Lynn Camp Prong. Basically, all of the rainbows above the Cascades are going to be first fished out (June 2-14?) and then the remaining fish will be poisoned later. The stream will then be closed while it's restocked with Brookies and closed for a few years until the Brookies have taken hold.
