Anyone fish the lower Castor river? We've got a trailer on hwy 34 and it is really clear cool water. My son set a limbline with a live bluegill and caught a 3 lb flat head. I've floated down the river for a few miles and the further you go it seems to get muddier and more stumps. Around the Zalma area looks really good but didn't know how much fishing presure it got. Not a very big river at all.
