Hey there, anglers! Artificial Lure here with your Colorado River fishing report for March 12, 2025.

The weather's been a mixed bag lately, with temps ranging from the mid-40s to low 60s. We've had some scattered showers, but nothing too heavy. Today's looking partly cloudy with a high of 58°F. Sunrise was at 6:23 AM, and we'll see the sun dip below the horizon at 7:11 PM.

Now, onto the fishing! The spring runoff hasn't kicked into high gear yet, so we're still seeing decent clarity in most stretches. Water temps are hovering in the low 40s, which means the trout are starting to get more active.

Rainbow and brown trout have been the stars of the show lately. Anglers working the deeper pools and seams have been pulling in some nice 14-18 inchers, with a few bigger boys in the mix. We've also seen a uptick in mountain whitefish catches, especially in the faster runs.

For you fly fishers out there, midges are still the main course. Size 20-24 black or red midges have been producing well. As we move into mid-March, keep an eye out for blue-winged olive hatches in the afternoons. Nymphing with stonefly patterns and small mayfly nymphs has also been effective.

If you're more of a spin fishing enthusiast, small gold or silver spinners have been doing the trick. Don't overlook the trusty nightcrawler either – the trout seem to have a sweet tooth for them right now.

For hot spots, I'd recommend checking out the stretch below Pumphouse Recreation Area. The deep runs and pockets there have been holding some nice fish. Another good bet is the area around Radium – the mix of riffles and pools provides plenty of holding water for hungry trout.

Remember, the regulations changed this year, so make sure you're up to date on the latest rules. Catch and release is encouraged, but if you're keeping fish, stick to the daily limit of four trout.

That's all for now, folks. As always, tight lines and stay safe out there on the water!
