The fisheries are:
Llanidloes
A typical upper Severn water with very good winter grayling fishing it has both wooded and open sections, good pools and fast stickles. The beat enjoys good hatches of fly and the trout can, at times, be free rising but late evenings provide the best opportunities during the summer months or at times of low water. There are also occasional salmon present late in the season.
Penarth
A main slower section of river above Penerth Weir with fishing primarily for chub, dace, grayling, brown trout and the occasional salmon.
Newtown
A mainly open stretch with fishing for chub, dace and brown trout.
