With longer days, creeks beginning to rush, and lakes melting out, Mammoth Lakes is ready for Fishing Season! That means the return of our monthly Fishing Newsletter, which provides the inside scoop on the best of Eastside fishing.

As of March 26, Crowley Lake and Convict Lake were ice free. Twin Lakes in the Mammoth Lakes Basin was still frozen with water beginning to spill out at the opening near the outlet. As is typical this time of year, snow storms continue to come and go. However, spring temperatures should keep clear waters open and ready for the season at this point, and continue to melt out the lakes that are still covered in ice.

While you can fish at certain locations year round in the Mammoth Lakes’ region, the fishing season opener lovingly known as Fishmas really kicks the hype into full gear. This year Fishmas falls on April 27, so start prepping your bait, boats, and barbs, and read on for the latest updates on fishing this season.

Responsible recreation in Mammoth Lakes means respecting our unreal natural surroundings and adhering to Leave No Trace principles. When exploring outdoors stay on designated trails, properly dispose of waste, and minimize your environmental impact. Everyone has a role to play in maintaining the beauty of this picturesque destination for future generations.

Fishing line can cause quite the tangle if it gets stuck around bushes, logs, and other shoreline and submerged obstacles. Do your best to untangle and retrieve all the fishing line you can and dispose of it at a Tangle Free Waters station.

If you plan to combine fishing and camping, bookmark for the most up-to-date information. Before pitching your tent, review these best practices for camping responsibly.
