Chris,
Google Earth................
Seriously. I usually float those rivers but have just banked it from time to time. Google the area around Forks and look for roads to rivers. This time of year and given the lack of rain, the HOH is your best bet. Northbound on 101, just after you cross the Hoh river bridge, at the top of the hill is a road off to your left. Take it, it goes all the way to salt water. Fish are scattered all the way to the Olympic Mountains but the numbers are from 101 down. If you want to bank really close to your cabin, there is good access to the lower Quil. Ask your folks at the resort. They can tune you in. Too hard to describe the roads. Given where you are staying, you might hook fish from your front yard. That hole is one of the best around. Fish come up and stack there.
Lower Duc has spots to bank and given the water levels, I wouldn't advise it in a hard boat right now anyway. Here again, Google it. I have....
Problem with the Duc and many of the OP rivers is access and numbers of fish. Low water season and VERY scattered fish. Lots of guides banging the water too. Rivers went to catch and keep nates so it's a little bloody out there right now.
PM me for any questions
good luck.
