Sections of the Ruby River
There are a handful of pullouts and access points. Right below the dam, there are two public FAS access points in the upper three miles. Below the first three, there will be another two access points within the next six miles. A great bet for anglers is parking two cars and walking a section between access points, staying in the water, and being mindful of private land.
The water below the reservoir is characterized by tight bends, wood structure, and buckets or drop-offs. Some of these buckets can hold multiple fish simultaneously; nymphing down to them can be very productive. Streamer fishing and quickly covering water can produce the willing, hungry, larger browns. In terms of dry fly fishing, a solid PMD hatch can come off. If the fish are not rising strongly during the hatch, consider throwing PMD nymph patterns and swinging them higher in the column; some forget that fish feed 90% of the time subsurface!
After the short canyon section, the river will transition into a meandering, open agricultural valley for the next 40 miles. This is where we tend to find the struggles of private land access where the Ruby flows through. If careful with public and private access, one that fishes these waters will find less pressure and less fish per mile, but great sized, willing fish in small water to eat large, foam attractor dry flies, terrestrials, and small heavy streamers.
From the top of the Ruby Mountains, snow melts and runoff drains to one of the gorgeous valleys in Southwest Montana. A small stream known as the Upper Ruby River begins as the smallest volume of water, trickling down gravel beds cutting through undercut, grassy banks. It makes its way down toward Ruby Reservoir. It grows in size as it fills from over a dozen other small freestone creeks from the mountains.
The distance from the first 15 miles on National Forest trickling water to the valley flowing water near the reservoir adds up to 40 miles. The upper Ruby doesn’t hold the largest fish, but it has the numbers to have a fun day. The fish average between 8-14″ and consist of browns, rainbows, cutthroat, big whitefish, and even grayling. Fish of this size tend to be quite eager, and these Ruby River fish especially love to come up and eat dry flies. There is an abundant stonefly population in the upper Ruby; throwing small foam attractor patterns to imitate golden stoneflies or terrestrials will fool these fish. If a dropper below the foam is put on, get ready to have a fun day full of lots of action!
Seasons on the Ruby River
Fishing in the spring can be very productive. During runoff, watching water levels is extremely important. If large spikes inflows, stay off the water and wait for the straight line; consistent flows will get the fish behaving back to normal. Baetis and midges will pop off every day in spring, just like many other tailwater streams in the spring. Also, caddis can be found amid these hatches, especially on a warm evening. Nymphing in the spring as the temperatures are still on the cold side will be most productive. Using natural color midge and Baetis nymphs will produce dropped below your bigger rubber leg or worm. Fish the buckets and deep, inside and long seams. Also, springtime calls for streamers as fish are coming out of winter looking for a big meal.
As spring progresses and the temperatures rise, runoff is in full bloom. Ruby Reservoir fills up in large volumes from the snowmelt and lets out a great amount of water through the end of May and throughout June. It is very tough and dangerous to wade fish during this time, but if the flows are in the fall, nymphing deep in the side eddies before everyone else does will help you catch the fresh fish of the season.
Once July hits, the fishing is game on. The bugs start to hatch, and dry flies can get fun on the Ruby River. Anglers will pull out their terrestrials and foam dry flies to run the dry-dropper rigs. PMD’s fish well in July too. When everyone is nymphing or throwing dries, wake up extra early or stay out until the sun drops dead drifting streamers deep or pulling them across fast to find that larger fish that everyone couldn’t fool throughout the day. Sculpin patterns or coffee sparkle minnows to imitate baitfish are great bets all season long, especially in the fall.
The Ruby stays open all season long, so spawning brown trout in the fall make for a fun streamer bite. Of course, it is proper to stay away from redds and let these fish do their thing. Work these fish on cool days in early October to find these browns in prime colors and hungry in Pre spawn.
The wintertime can be productive on the Ruby. When a warm Montana day comes along, a quick walk and wade section with dry fly fishing midges can be fun. Also, fishing during peak warm hours throughout the wintertime will better help the bite with active fish. Fish will pod up and work the midges. Using smaller Baetis and midges under an indicator with a subtle approach nymphing in the low water could also be very productive. Getting deep into those fish during the winter months can produce some bites as there is much less pressure throughout the winter months.
