No special access issues
Park next to the road by the pavement (NOT up by the road stop) and walk up to the lake. At the lake take the left road and when it later forks again keep walking left until you reach a small path that turns right, into the woods.
(Certain times a year the road block is open, but mostly not)
Fishing is prohibited unless you posses a fishing card for the area.
Swimming in the lake is ok as long as no boats/floaties are used.
