Parking at Lake Chabot (Lake Chabot Rd)

I pretty much come here nearly everyday and usually park on the street but on holidays and weekends like today it’s super crowded and I find myself doing a bunch of u turns just to find parking on the street so I don’t have to pay $5 daily to park in their parking lot.

Does anyone in here know if they have like a yearly or monthly fee that makes it more affordable to park in their parking lot?

I would ask them but no one was at the parking booth when I was there today.
