Havyatts Drain, Double Bay. Where: Double Bay. Youll know because its name is written above it! Log: 12/2005 1st time Howie & half of Sydney Caveclan. (Thanks to the CC for having me along on their Expo) Photos: None by me. I kindly accept donor photos by permission :) Interest: 3/10 Warnings: Don't go if its raining or looks like rain. Grumpy old lady in house besides drain says "Your not allowed to go in there" Der! Best at Low Tide or your going to get wet exiting the harbour end. Walk out at low tide. Careful of sharp Oysters. Walk in Middle nearing end. Equipment: At least one torch each with good batteries. Rubber soled shoes are a must. Description: A great drain for the beginners. Canal access. Over the fence, or a little further down the canal till you find step irons and a hole in the cyclone fencing. Hey, why not go through the ladies front yard with the missing fence pailings. If she catches you please quote: "Sorry, we wont do it again" Seemed to work alright for Syme and no police attended, so win win! 12ft wide Concrete base & side construction with natural rock ceiling. Drain is the one on the far right with the name written above it. I forgot to ask the Clan how it was named. Entry is a stoop increasing to 8ft for remainder of journey out to Double Bay. Concrete floor gradually gets sand covered and oyster covered near the exit. Notice the old compactor machine up on a ledge RH side near the exit. Also the old insulators hanging from the ceiling for contruction lighting (long gone). Of interest where the occasional Eel which I stepped on one (sorry lil fella) and a few small bait fish. Exiting at low tide in the bay via stair case on your right and up the left hand side of the block of units. Laundry available on your way out if you need it! Follow the road back to where you began or hoik it back up the drain to the entry point. Lots of fresh air ventillation so dont fret when you see the confined space sign (complete with Gas Mask symbol) at the harbour exit. You will get wet feet at low tide, no higher than your ankles incase you where wondering and this presumes no rain.
