Post-spawn bass and Lees Ferry trout in reach as Colorado River holds steady

What's Biting

What's Next

Looking ahead through the first week of June, the Colorado River tailwater at Lees Ferry appears stable. With flows registered at 9,960 cfs, the river is in a productive band for both drifting and wade-fishing. Glen Canyon Dam releases can shift day to day based on downstream power demand and reservoir management, so anglers planning a float or wading session should pull the latest release schedule from the Bureau of Reclamation before launching. A modest uptick in cfs, particularly if releases increase toward midsummer generation peaks, could push fish deeper into main-channel seams, making longer nymphing drifts and heavier tungsten rigs the more reliable approach.

For trout at Lees Ferry, 61°F sits near the feeding sweet spot for this tailwater. As June deepens and ambient air temperatures in the canyon climb into triple digits, expect fish to concentrate in deeper, shaded sections of the run. Early morning and late afternoon sessions will be most productive as the surface heats through midday. Subsurface presentations including soft hackles, beadhead nymphs, and San Juan worms should continue to outperform dry-fly fishing during the heat of the day.

On the Salt River, bass are moving through the transition from post-spawn recovery into summer feeding mode. Per Tactical Bassin's June analysis, bass are shifting toward isolated offshore structure, including points, ledges, and submerged rocky shelves, and can be targeted effectively on reaction baits like chatterbaits in the morning before switching to finesse presentations (drop-shot, neko rig) as the sun climbs higher. The next two to three days under a Last Quarter moon should produce low-light windows that favor topwater and shallow presentations at dawn and dusk.

Catfish will continue to improve as water temps push further into summer ranges. Look for channel cats in deeper, slower-moving bends and eddy pockets. Fishing the Midwest points out that rivers can deliver outstanding warm-weather action in precisely these kinds of structure-heavy stretches.

Weekend anglers should plan around early-morning starts given Arizona's June heat. A launch before 6 a.m. puts you on prime water during the coolest, most productive window before afternoon temperatures push into uncomfortable territory for both anglers and fish.

Context

For early June in Arizona's river system, a 61°F water temperature at Lees Ferry is consistent with typical tailwater behavior for this time of year. The Colorado River below Glen Canyon Dam maintains relatively stable temperatures year-round thanks to cold water released from depth at Lake Powell, but as summer generates peak power demands, release volumes often increase and with them, flows can rise and drop abruptly. Historically, June and July bring the most variable day-to-day release schedules on this stretch, so gauge-watching matters more now than in spring.

For the Salt River's trout water below Saguaro Lake, June typically marks the tail end of comfortable conditions before midsummer heat stresses fish in lower-elevation sections. Trout anglers familiar with this tailwater know that June can deliver excellent early-morning sessions before surface temperatures push into less favorable ranges for the fish.

The angler intel feeds surveyed for this report do not include Arizona-specific dispatch this week. The regional blogs and forums available were primarily covering Midwestern walleye regulations, Northeast striper migration, and Southeast and Great Lakes bass patterns. The closest parallel comes from Hatch Magazine's piece on fishing through drought conditions on Colorado's Front Range. Its core observation applies here as well: dry years tend to concentrate fish in tailwater sections and deeper pools, making gauge-managed rivers like the Colorado at Lees Ferry more reliable than free-flowing streams when precipitation runs below normal.

Bass on both the Salt and Colorado are typically in post-spawn recovery or early summer feeding mode by the first week of June at Arizona's lower elevations, on schedule with what Tactical Bassin's June reports describe for the broader region. Catfish historically peak through summer nights on these rivers, and nothing in this week's feeds signals a departure from that pattern. Overall, conditions appear on track for what AZ river anglers expect heading into the hottest months.
