RMA Poudre Rock Report

I learned from the great Maddox why the Riv has experienced such a precipitous drop off. Apparently we are working on a kill off of non-native species in the upper reaches of our watershed. So, effectively we are looking at a complete kill off of all, and reintroduction of preferred native fish. To do this, they shut off the spigot. I guess the conveyance from Poudre Lake to the main stem of the Poudre will be the next target. Fingers crossed the mission is successful.

Currently 80˚f, overcast and calm. A 40 percent chance of showers and thunderstorms after noon. Mostly cloudy, with a high near 85. West southwest wind 8 to 10 mph, with gusts as high as 16 mph.
Tonight: A chance of showers and thunderstorms before 9pm, then a chance of showers between 9pm and midnight. Mostly cloudy, with a low around 62. West southwest wind 6 to 10 mph, with gusts as high as 16 mph. Chance of precipitation is 40%.

This may be the last weekend for The Rock Report this 2026 Season! That of course is always subject to change, should something significant happen. I will continue to post relevant information and events to the site, so keep your subscriptions active and stay tuned.

Currently 54˚F, blue skies and calm.

Actually, if there was a line at 0.0, we would be in the negatives this morning. She was good while she lasted (thanks to Greeley senior water rights and our capacity to “borrow” water from other drainages). On the drive down this morning, the Filter Plant is a bone yard!
