    ‘Climate change is water change’

    Climate change is water change. A warmer climate impacts nearly every facet of the water cycle: increased evaporation and transpiration deplete water from the land, rivers, lakes, oceans, and forests. Warmer air retains more water that is later released through intense precipitation events that are more likely to cause flash flooding and run-off pollution.

    By Chase S. Whiting As summer transitioned to fall, the sun hung eerily over the Adirondack Mountains and illuminated smoke that traveled some 3,000 miles from wildfires out West. Seeing the smoke reminded me that seemingly distant corners of the planet are in fact interconnected by our shared environment.  In Vermont, the climate change story…

    First look at Denali

    I'd come all the way to Alaska and saw more grayling than I'd ever seen in one place. And I didn't catch a single one from this river. And I didn't mind a bit

    Denali shrouded in storm clouds

    With a view like this, a fishless day isn't too bad after all Just a glance over the side of the canoe revealed the life swimming in this crystal-clear spring creek situated just off the Alaska Highway about a 100 miles southeast of Fairbanks. Big Arctic grayling—and some of the biggest whitefish I'd ever seen—cruised…

    Habitat connectivity helps trout take care of themselves

    If we do our part to remove migration obstacles from rivers and streams, the fish will take care of the rest. The benefits could be immeasurable.

    By Brian Hodge In our work at Trout Unlimited, we often rely on scientific theory to plan and implement conservation projects. In some instances, we also test hypotheses by monitoring projects and comparing predictions with outcomes, and in doing so contribute towards the broader body of scientific theory.   For TU and our local agency partners, the…

    TU and BHA team up on membership

    To say that 2020 has been a challenging year would be an understatement. But perhaps what the year has provided us is an opportunity to reflect on what’s really important. What matters to all of us? Family and friends. Fishing, hunting and outdoor adventures. Our public lands and waters. These places give us so much,…

    Tying the Repeat Offender

    Trout spey fishing is all the rage these days, particularly in rivers that boast runs of anadromous fish that are swimming home and reacquainting themselves with fresh water and the food they used to eat before they took the salt to dine on the ocean's bounty. Below, Matt Callies with Loon Outdoors ties a great…

    Desperately seeking steelhead in Alaska for science

    After a long float plane flight back to Juneau, a hurried meal and a handful of Ibuprofen, I turned in for the night with one last thought – Tomorrow. Tomorrow we’ll find the fish and all of this will be worth it.

    By Mark Hieronymus After the first couple of hard-earned, bushwhacked miles, about the time we had fished every inch of beautiful holding water in this wild, remote river, and just after we finished post-holing our way through a couple hundred yards of thigh-deep snow, I started to second-guess myself.  Months of reviewing fisheries and habitat…
