Eastern Sierra Sustainable Recreation

Eastern Sierra Sustainable Recreation While our page name has changed, our mission remains the same: to share sustainable recreation messaging across California’s Eastern Sierra.

This page started as a messaging tool for the Eastern Sierra Sustainable Recreation & Tourism Initiative, and was named "ESSRP Sustainable Recreation & Tourism Initiative". The "SRTI" was implemented July 2019 - January 2022. For additional information about what was accomplished: https://mltpa.org/essrp/sustainable-recreation-and-tourism-project. On May 1, 2025, the page was rebranded and moving

forward, this page will share sustainable recreation messaging across California’s Eastern Sierra. We are excited to share that our page is now EASTERN SIERRA SUSTAINABLE RECREATION. While our name is changing, our mission remains the same: to share sustainable recreation messages and projects across the Eastern Sierra. This update reflects a broader and more lasting vision (beyond the original SRTI) that honors local partnerships, uplifts community voices, and supports responsible recreation. This helps ensure our public trails, waterways, mountains, and open spaces are accessible today and for future generations. Follow along as we continue to share stories, celebrate stewardship, and encourage respectful exploration.

Whether you are headed to Diaz Lake in Lone Pine, the high alpine waters of Rock Creek, or the legendary Crowley Lake, new watercraft laws are now in effect across the Eastern Sierra.

Invasive Golden Mussels are a severe threat to our region. To protect our pristine waters, we have new requirements for all boaters:

📍 FOR TRAILERED BOATS (Mandatory):
If you are towing a fishing boat, ski boat, deck boat, or pontoon, you MUST stop at an official Watercraft Inspection & Decontamination (WID) station in Bishop or Bridgeport before you head to the ramp.
🎫 NEW LAW: A valid Eastern Sierra Mussel Sticker must be displayed on your trailered vessel before launch.

📍 FOR ALL OTHER CRAFT (Kayaks, SUPs, Float Tubes):
While hand-launched craft do not require a formal WID station stop, you are still legally required to ensure your gear is Clean, Drained, and Dry 🧼💨 before entering any waterway.
📍 WATERS COVERED:

These laws are strictly enforced for ALL Inyo and Mono County waterways, including:
🔹 Diaz Lake & Klondike
🔹 South Lake & Lake Sabrina
🔹 Rock Creek Lake & Convict Lake
🔹 Mammoth Lakes Basin (Twin, Mary, George, Mamie)
🔹 Crowley Lake, Grant Lake & June Lake Loop
🔹 Bridgeport Reservoir ...and everywhere in between!

⚠️ THE STAKES: Launching a trailered boat without an inspection can result in heavy fines or boat impoundment. Protect the places we love—inspect before you connect! 🌲✨

The countdown to the regular season opener on April 25 is ON! As you prep your gear, there is a new "must-do" on every Fishmas checklist to keep the invasive Golden Mussel out of our backyard.

Don’t let a citation ruin your Opening Day:

PLAN AHEAD: Expect a stop at a Watercraft Inspection &
Decontamination station before heading to the lake.
Check https://na2.hubs.ly/H052lSS0 for WID locations and details.

NO STICKER, NO LAUNCH: Mandatory inspections are now LAW across Inyo and Mono County waters.

CLEAN. DRAIN. DRY. INSPECT: Make sure your boat and gear are 100%
dry before you arrive.

Don't risk your boat or your season! Let’s keep our waters pristine for
generations to come.
