I'm sorry your trip was less than you hoped in the fish catching department. It's been a tough few years on the lower Deschutes. It's my local steelhead river and I haven't fished it in August or September for a couple years because of the off color flows caused by the White River. This year has been even worse with muddy flows continuing well into October. Until we get a few winters with good snowpack to build the White Glacier back up a little I think this is just going to continue and perhaps get worse.
