mate it depends are you talking about the depot beach launch or north durras or south durras launch
depot beach is a tough option in any condition and is at most recommended for zodiacs
north durras boat ramp has long since seen its best days and is now more a clay track than a boat ramp
south durras is a far better ramp leading down from a high quality caravan park it is still relatively well maintained
however all of this may be useless as when i spoke to mates down there and when i was there bout 8 months ago the lake was closed.
any other questions feel free to give us a holla as im down there generally 2-3 times a year a nice spot very quiet for 11 months of the year.
