Wildfire preparedness starts at home.

Join the Mammoth Lakes Wildfire Task Force team to learn about ongoing efforts in and around Mammoth Lakes to build wildfire resilience. Find out how you can help protect your home and neighborhood through home hardening and defensible space practices.

This Friday, June 26 from 5-7pm, the team will be stationed at the corner of Manzanita and Dorrance. Stop by, say hello, ask questions, and enjoy FREE BBQ!

2 Green waste dumpsters will also be available 6/24-6/29 along Dorrance to help residents clear vegetation and create defensible space around their properties.

Schedule your free defensible space inspection at:

🚧 PANORAMA DOME TRAIL CLOSURE 🚧

Forest health and wildfire risk reduction work will take place in the Panorama Dome area from June 22–30 as crews complete the second year of treatments in this area.

The trail segment connecting Old Mammoth Road to the Panorama Dome trail network will be closed, along with the adjacent Forest Order Closure Area shown on the map.

Trails outside of the closure area remain open.

Please obey all posted signs and closure notices and do not enter closed trails or forest areas. These temporary closures are important public safety measures while crews conduct active forest health work. Thank you for your patience!

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! 🌲✨

Please bring a reusable water bottle, sunscreen, sun protective clothing, closed-toe shoes, and work gloves, if you have them. We will begin work at 9:00am and wrap up by 2:00pm.
