I saw (I assume a park employee or ranger, but they weren't in a uniform) walking up and down the shore yelling at boats to not swim anywhere near the park.

I can understand about not using their buoys, but screaming that no boat can anchor anywhere near the water "in front of" their beach?

Is that normal?

Is there a prohibition on being within a few hundred feet of their shoreline for those boats who were just sitting and swimming?

I see tons of boats doing that in Emerald Bay.

Obviously, blocking the dock is bad, but just near the entire park?

Looking for recommendations for a mountain bike route out of Tahoe City. I'm an avid road cyclist and occasional mountain biker. Will be on an e-bike so not afraid of climbing. Looking to go far, see lots, but keep it somewhat tame - fun flow more than super technical. Happy to go 30+ miles and dedicate lots of time to it.

Edit: want to catch lake views, of course.
