No you guys are wrong...boskop is just outside of potch on your way to carletonville on the rysmierbult road...i fish there quite often...
Boskop is a nature reserve, the water of this dam flows into potch dam...really nice dam just allot of grass, the water is also very clean one of the cleanest dams ive seen, but that makes good fishing for bass!!!The bass there is really good sizes!!You can camp there too,very good prizes but no electricity.
Check it out.
Im going there again in spring!!!
And in October.
