Diamond is a very good rainbow fishery in the spring and fall and is worth the drive to this more remote setting. There are plenty of good places to fish Diamond Lake but getting around to all of them in one day will require a motor boat.
For row boats and tubes simply pick a launch point and stay there, you’ll likely still have a great day of fishing and catching.
Diamond Lake is another lake with excellent shoal areas the harbor not only good populations of trout, but an abundance of aquatic insects for the fish to eat too. Callibaetis hatches are strong here in May and June, damsels hatches follow the callibaetis but nymphs seem to work almost any time during the season.
Leech patterns are excellent here especially fished on a hover or clear camo line. In the spring and fall I’m not sure if a leech is better or if a chironomid is best, but both methods will fool your fair share of trout.
Diamond Lake is closed in the winter and covered in ice and deep snow. At over 5000 feet above sea level it can be slow to thaw out, but usually is open in early May and remains good well into October.
Diamond has 5 boat ramps but the South Shore and Resort are the 2 I use most. Getting to Diamond Lake is a longer drive but it’s easy on good paved highways.
From Bend take Hwy 97 south to Highway 138 and head West on 138. Crater Lake National Park is near here so a side trip to one of our countries finest National Parks is in order for sure.
