    This should be good for flushing out the river. It’s probably long overdue. SH and NSW get more than their fair share (~95%+) of water that would otherwise reach Victoria.

    In terms of more medium term trends a constant rise in Burrendong Dam, i've never visited is it a very shallow dam? I do like monitoring it's levels though.

    This system put about a metre of water into the Wonboyn waterway: https://manly.hydraulics.works/Site-220452

    The entrance was closed a few weeks ago, saw some pics today with it raging and plenty more water to come out.

    Yeah, never seen it so high. I was at the not so secret crossing down stream post bushfires but before the first main rain event of the year and it wasn't flowing.

    Mates up in Wollombi are still cut off from town. Been a while since it had a good flood.

    BURRENDONG DAM

    [​IMG]Burrendong Dam is situated on the Macquarie River just below its junction with the Cudgegong in the central west of New South Wales. The headwaters of the Macquarie River were discovered in 1813 by Deputy Surveyor G. W. Evans, who named it after the Governor of the day. Wellington is about 30 kilometres downstream and the nearest settlement is Mumbil, some eight kilometres away.

    [​IMG]Burrendong Dam was proposed immediately after World War II as a means of improving water supplies and boosting agricultural production in the Macquarie Valley. Construction commenced in 1946 but due to financial limitations the dam was not completed until 1967.

    The name Burrendong is one of the Australian Aboriginal words for the koala.

    Burrendong Dam is a very large inland storage. It has a capacity of 1 678 000 megalitres, which is about three times the capacity of Sydney Harbour. The dam has a potential 489 000 megalitres air space for flood mitigation.

    The main wall is an earth and rockfill structure 76 metres high, with a crest length of 1116 metres. The surface area of the stored water is 89 square kilometres and the catchment area covers 13 886 square kilometres. Maximum water depth is 50 metres.

    [​IMG][​IMG]Flood outflows pass to the river by way of a concrete spillway situated about one kilometre northeast of the dam. The spillway is operated by seven radial gates each 16.8 metres wide and six metres high.

    I can say from experience that when it is 140% full (like it was in 2016) you feel like you are on the edge of the ocean when you are looking eastward from the dam wall. Longest continuous line of sight over water is about 8km.

    Go have a look, the Snowy below IB is powering more than it has since before the hydro - both the Gungarlin and Burrungubbee are flowing into it.
