Merced River Fishing Guides and Conditions, California

The river of Yosemite Valley, a snowmelt-driven Sierra freestone with wild rainbows above the park boundary and a famous spring whitewater season below it.

Claimed profiles take booking requests. Unclaimed profiles are built from public records so the river is never empty; the guide can claim or remove one any time.

About the Merced River

The Merced rises on the shoulder of Mount Lyell, falls through Nevada and Vernal Falls into Yosemite Valley, and then drops west out of the park toward the San Joaquin. The gauge at Pohono Bridge sits at the lower end of Yosemite Valley and watches three hundred and twenty-one square miles of almost entirely protected high country. It reports discharge and stage but no live water temperature, so flow alone is the planning number, and on a snowmelt river that number tells most of the story anyway.

This is a snowmelt hydrograph in its purest form. The Merced runs enormous in May and June, when the Sierra snowpack releases and the river through the valley becomes loud, cold and genuinely dangerous, then falls away through July and August to a low, clear late-summer flow. Fishing follows that curve exactly. The river is essentially unfishable at peak melt, comes into shape in July, and fishes best from late summer into autumn when flows are low and the wild rainbows in the valley and the upper canyon are looking up.

Fishing inside Yosemite is a wild-trout affair rather than a trophy one. The rainbows are small, native-descended and unstocked, and park regulations are restrictive by design. Below the park boundary along the Highway 140 corridor the river holds larger fish, including browns, and is stocked in places.

The commercial guiding on this river is more often whitewater than fishing. The stretch below El Portal is one of California’s classic spring runs, a steep pool-drop canyon that only has water for a few months, and outfitters there work a compressed April-to-June season built entirely around the melt. Anyone planning a trip on the Merced should therefore decide first which river they want, because the whitewater season and the fishing season are almost perfectly non-overlapping and no single week offers both.

1. What you give us

By ticking the box on the form you grant Guided Floats, LLC (“GuidedFloats”, “we”) a non-exclusive, worldwide, royalty-free license to store, copy, resize, crop and display your photograph on guidedfloats.com, in GuidedFloats’ own social media accounts and mobile apps, and in material that promotes the site itself, in connection with the fish, water or community feature you sent it in for. The license lasts until you withdraw it (section 4).

You keep the copyright. The license is not exclusive, so you can use the photo anywhere else and license it to anyone else. We will not sell your photo, license it on to anyone else on its own, or use it in paid advertising for a third party.

2. What you confirm

You confirm that you took the photograph yourself (or otherwise own the rights to it), that you have the right to grant this license, and that publishing the photo does not infringe anyone else’s copyright, privacy or other rights.

If any person is recognisable in the photo, you confirm that they have agreed to its being published here, and that a parent or guardian has agreed on behalf of anyone under 18. Please do not send photographs of other people’s catches, screenshots, or pictures copied from other websites or social media.

3. Credit

We print the credit name you give us beside the photo wherever it appears on the site, and record it as the photo’s creator in the page’s structured data. If you leave the credit blank we use the name you gave us on the form. Write “Anonymous” if you prefer no name at all. Your email address, phone number and the exact spot the photo was taken are never published.

4. Withdrawing the license

You can withdraw the license at any time by emailing hello@guidedfloats.com, or by using the contact form, and telling us which photo you mean. We will remove the photo from guidedfloats.com within 7 days of receiving your message and stop using it in anything new. Copies that are already outside our control — search-engine caches, social posts that have already gone out, printed material already produced — may take longer to disappear or may not be recallable, and we are not responsible for those.

5. What we may do

We choose which photos to publish and may decline any submission without giving a reason. We may crop, resize, sharpen or colour-correct a photo for display, and we may remove a photo at any time. We will not alter a photo in a way that misrepresents the fish, the water or you.

6. Your details

We keep your name, email address, the credit name, the water and date you gave us, and the network address the submission came from, with the submission record, as our evidence of this license. We hold that record for as long as the photo is published and for the retention period described in our privacy policy. Location data that your camera or phone embedded in the file is removed before the photo is published.

7. Versions

The version of this license you accepted is stored with your submission and printed with the photo. A later version does not apply to a photo you have already sent unless you agree to it.
