Fishing on Mt. Lemmon: The Complete Trout Fishing Guide
Want to fish for rainbow trout in a pine-ringed mountain lake, 45 minutes from downtown Tucson? Welcome to Mt. Lemmon — Arizona's famous sky island, where the desert floor gives way to 9,000-foot forests and some of the best trout fishing near Tucson. The centerpiece is Rose Canyon Lake, a stocked trout lake tucked into a stand of ponderosa pines at about 7,000 feet.
This guide covers everything: where to fish, when the trout are stocked, what you need to stay legal, what gear to bring, and where to stay so the lake is minutes from your door.
Rose Canyon Lake: The Star of Mt. Lemmon Fishing
Rose Canyon Lake is a small (about 6 acres), beautiful, ecologically fragile lake high on the slopes of the Santa Catalina Mountains, surrounded by tall ponderosa pines and rocky slopes. It's the mountain's only real lake fishery — and the reason "fishing on Mt. Lemmon" is such a popular day trip.
- Stocked with rainbow trout roughly once a month from early April through the end of August — fish large enough to take home
- Brown trout are also stocked, usually once in late fall as fingerlings, so holdover fish keep the lake interesting year after year
- Fishing is best early morning or just before dark, when the lake is calm and the trout are feeding
- The easy Rose Canyon Lake Trail #37 loops the water's edge, with a handicapped-accessible path and floating dock near the dam
- Day-use fee: $11 per vehicle (walk-ins $1 per person) — the concessionaire does not accept federal passes here

Why Rose Canyon Lake Is the Only Real Fishing Spot
Mt. Lemmon's creeks (like Sabino Creek near Marshall Gulch) run seasonally — flowing in spring and after monsoon rains, then drying back up — so they don't hold fish. If you want to catch trout on Mt. Lemmon, Rose Canyon Lake is the spot: the only real fishery on the mountain, and the one place you can count on stocked rainbow trout all season long.
Skip the stream gear and head straight to the lake — it's easier to reach, more reliable, and the scenery is just as good.
When to Fish: Seasons & Stocking
- Season: roughly April through October, weather permitting. The entrance gate closes in winter, but walk-in fishing is allowed with a valid license.
- Stocking: rainbow trout are released about once a month from early April through end of August, when water temperatures get too warm for cold-water fish.
- Fall: brown trout fingerlings are stocked once in late fall, building the lake's holdover population.
- Best times of day: early morning and dusk — calm water, active fish.
- Always check: conditions change fast on the mountain. See the Mt. Lemmon weather page before heading up, and check the official Arizona Game & Fish stocking schedule for exact weeks.
Licenses & Rules (What You Need to Stay Legal)
- A valid Arizona fishing license is required for anyone 10 and older — buy it online at azgfd.com or at local sporting goods stores before you go.
- Daily bag limit: 4 trout in any combination; possession limit is twice the daily bag.
- No swimming, boats, or camping at the lake — it's an ecologically fragile fishery.
- Dogs must be on a leash.
- Pack out what you pack in — use the trash bins and don't litter.
Gear & Tips for a Great Day
- Rig: a light or ultralight spinning rod is perfect from shore. A telescoping rod travels easily.
- Baits that work: PowerBait, worms, salmon eggs, and small spinners; fly anglers do well with small nymphs and dry flies during hatches.
- Layers, always: it's about 30°F cooler than Tucson up here — a sunny morning can turn breezy fast.
- Sun protection: at 7,000 feet the sun is strong — hat, sunglasses, sunscreen.
- Water & snacks: there's no potable water at the lake, so bring your own.
- Comfort: a small chair or stool makes shoreline fishing much more enjoyable.
- Altitude: if you're coming straight from Tucson, drink water and take it easy at first.
More to Do Around the Lake
- Hike the loop: Rose Canyon Lake Trail #37 circles the water — an easy, family-friendly walk with views from the dam. More trails on our Mt. Lemmon hiking guide.
- Picnic: shaded picnic areas and vault toilets are on site (no potable water).
- Camp nearby: Rose Canyon Campground sits right beside the lake — see our Rose Canyon visitor guide for details.
- Make it a day trip: pair the lake with the best of the mountain — see our day trip from Tucson and the full Things to Do on Mt. Lemmon hub.
