It wouldn't have any effect on Snowy Hydro. Anything below Jindabyne Dam is lost to them, the snowy doesn't even flow between Island Bend and Jindabyne, and they didn't get that much rain above Island Bend. That warning was for the lower Snowy.

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.

Better than you thought with 1 GL/day inflow from 27th and rising with all this rain events runoff to come. So 10% jump this week and more next. Forded the Dixons Long Point crossing on Macquarie R. last Sunday week.It's a little deeper today having risen 2 m and in need of that $20 million bridge LOL.... W
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.

BURRENDONG DAM

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.

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.

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.

Suns out on the Jindy North Shore with the Main Range shining brightly and the faint sound of edges being sharpened wafting on the breeze

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.
