Is the swim beach open?

I thought I read that it is open

I just ride my bicycle to the reservoir have a sandwich and th north Marina. They don't allow swimming I think , Th more you explorer , the more you have to think of if it's legal or not. Such as trespassing. Just obey, unless it's a dire emergency to help someone or disaster call an emergency person. Most of its common Sense stuff.stay in bounds marked paths , they have a lot of wild life , bugs, an activity, my favorite is how fast everything is built up sence the 70, ! Wow I met the person , grew up in a house underneath chatfield reservoir. used to live underneath chatfield reservoir . Don't know where this is going.

Yeah it's open
