Day 4 Lake Nagambie - Old Toolamba.
I began my paddle on Lake Nagambie before most people were awake. The water was still smooth as glass. There was almost a perfect reflection of the sky and the surrounding bush on the water. Lake Nagambie is a flooded landscape, there are islands of vegetation, each its own biosphere, which dot the shallow areas of the lake. Each small island is a refuge for all manner of land plants, growing on stumps of the forest that was here before the Goulburn Weir was built in 1893. I saw red gum saplings, bottlebrush, blackberries, grasses and understory shrubs growing on the stumps. They look like the unkempt hair on a teenage boy as they sprouted from their toe-holds into the overwhelming space of the lake. This is great kayaking country - so long as you get up early or come in at time of year where there is not too much boat traffic. In the quiet of the morning I saw black swans, spoonbills, rainbow bee-eaters, apostle birds, tree martins, the sacred Kingfisher and heard cockatoos singing the only way they know how, trying to clear the neighbourhood of all the competition. Turtles splashed into the safety of deep water as I approached. I am constantly amazed at how alert they are when they seem to be sleeping and how well they see, when their eyes are so small.

Black swans (Arkive.org) are common in Nagambie Lakes, with shallow backwaters providing shelter and plenty of water plants to feed on. A group of swans is called a bank. When they fly in formation they are called a wedge. Black swans can be nomadic. They mate for life. Both partners are involved in looking after the nest and bringing up the young. The scientific name 'Cygnus atratus' means 'a swan attired in black'. European explorers took examples back to Europe; some have managed to escape and establish wild colonies in England. The first birds taken to Europe were under the orders of Napoleon for his wife, Josephine. She was extremely fond of these birds because of their exotic nature and red beaks. Red spots were seen as a sign of beauty in France at the time, with ladies often sporting them on their cheeks. On the journey back to Europe, the swans were fed red wine and bread. Somehow they managed to survive (The rise and fall of Josephine Bonaparta: Kate Williamson ABC Radio National Late Night Live).

|Yellow Water Lily (Aquaplant.tamu.edu) increasingly a problem in waterways of the Murray Darling Basin. A native of Mexico, Yellow waterlily is increasing an alarming rate in Lake Nagambie and in channels and dams which feed from it, including the billabongs and waterways of the Gunbower Perricoota Koondrook Forest. Once established it can block waterways and is difficult to eradicate. New growth of this plant is mainly initiated vegetatively. Stolons are produced during spring to autumn specially following flooding. Stolons produce new plants at the nodes. (Emerging aquatic weeds in Victoria). All parts of the plant must be removed in order to remove it, or the lake drained and exposed to frost (as was done to lake Mulwala in 2013).|
|Most banks are covered by trees, but in some places, erosion is faster than the growth of the vegetation which otherwise might protect it. Perhaps an ancient sandhill?|

|Old bridge remains linking narrow points of land between the Eastern and Western Backwaters on Lake Nagambie.|
|Kirwan's bridge was closed for some time and a boulder placed at each end to stop traffic driving across it, however there was such an outcry from local and tourists, that funds were found for its repair and maintenance. It was reopened in 2011. ABC News Report on the re-opening of the bridge.|
|So significant was the access to Nagambie it provided for those living on the west of the Goulburn River that a threat to the bridge’s continuing future in the mid-1950s led to a municipal secession movement that enlarged the Shire of Goulburn at the expense of Kirwans’ original builders, the Shire of Waranga. The current narrowed timber deck with passing bays, supported by rolled steel joists placed over the ancient piers, remains a memorial to that municipal protest. It is one of Victoria’s very oldest timber road bridges still in operation; very few are earlier. Kirwans Bridge is also one of a unique group of four large timber road bridges from the 1890s, of contrasting types, located on the Goulburn River between Seymour and Murchison; this is the last remaining group of large old timber river bridges in Victoria. The 310 metres long Kirwans Bridge is situated over the Goulburn River at Bailieston near Nagambie. It was opened in 1890 and is still in use for one-way motor traffic. The only comparable timber bridge in Victoria in terms of length is the 1927 Barwon Heads Bridge which is 308 metres long. The bridge features a dramatic mid-stream bend and is also unique in its incorporation of two vehicle passing-bays. Source: Victoria for everyone|

|In the early morning and evening light, the lake is serene.|
|Water mirrors sky, a timeless scene. The Goulburn River Valley once supported a population of hundreds of members of the Taungurung (Daung wurrung) Aboriginal people. The country of the Taungurung includes the area between the upper reaches of the Goulburn River and its tributaries north of the Dividing Range; from Kilmore in the west to Mount Beauty in the east, and Benalla in the north and to the top of the Great Dividing Range in the south. Evidence of the Taungurung can be found in many places throughout Taungurung Country, and includes scar trees, rock shelters, rock art and place names. For instance, Nagambie or ‘nogamby’ means lagoon. (GMW). I think that the river in its quieter moments, would be a place where they could find peace.|
|Most trees from the pre-existing river bed are only stumps, yet this one survived over 100 years of inundation. The snags, stumps and trees all provide habitat for waterbirds and turtles.|
|There are extensive areas of shallow water around Lake Nagambie and the old river course, as well as underwater objects such as logs and standing trees. Such areas provide valuable fish habitat, however, they can also obstruct boating and present safety hazards (GMW). Without much of a current, these are difficult to see, so care needs to be taken when navigating these areas.|
|Meeting up with Ruth, I had to push through a bank of reeds.|
|Looking back into the lake from the boat ramp just in front of the weir.|
|The path from the boat ramp just before the Goulburn weir: closed to motor boats, but an easy exit point for canoes and kayaks. The track leads straight to the weir car park, where there are very good toilets and plenty of shade and green grass to relax on. To portage around the weir, call Goulburn Murray Water (03) 5794 5900 a couple of days ahead and arrange for the locked gate to be opened and (if you need it) transport for your boat to the ramp below the weir. If you throw your boat over the fence and crawl under, especially in front of their noses (the Nagambie office overlooks the weir), prepare to be yelled at. The gates are locked because of a recent drowning: a tourist was caught in a stopper wave at the base of the weir. We were advised that it is best to call ahead a couple of days beforehand, so that a staff member will be present (they travel all around the district inspecting irrigation infrastructure) and be keeping an eye out for you.|

|It must have been a long time ago that the road continued on straight ahead. This sign seems to be stating the obvious, but at night it could well be a life saver.|
|The original cast iron gates, stone base and generator house from 1891 on the Goulburn weir. Some of the gates which were dismantled when the weir was upgraded in 1987 have been transported to and reconstructed at the Australian National Museum in Canberra. GMW General Manager Catchment Services Graeme Hannan, said that two of the original piers, one gate and one section of a walkway have been donated to the Museum (GMW).|
|Water released as part of an environmental flow into the Lower Goulburn. Plan your trip to coincide with summer irrigation and environmental flows (call GMW to check when these are planned) and you will have more current and less trouble with snags.|

When the Goulburn Weir was built in 1891, it was the largest water engineering project in Victoria. It was built with sandstone hewn from nearby hills: as you walk over the weir (open weekdays 8am - 4pm) you can see them at the base of the wall. Unlike weirs on the Murray River, which were initially built to improve navigation for river trade by paddle steamers, the Goulburn Weir was built as a water reserve for irrigation. This scheme so excited people of the time, that it was featured on a bank note of the time. No expense was spared with its design. A hydroelectric generator was installed to operate the gates using electricity and lights installed to show off the spillway and weir structure. Special trains were chartered for people to picnic in its grounds and to admire the electric lights at night. Country sports days were held at the weir for many years and on Armistice day, the flags of all the allied nations were flown there. It was a symbol of national pride.

Three channels leave the weir, providing water for irrigation throughout the lower Goulburn Valley for fruit orchards and dairy production and town water supplies, and, via inter valley channels and the Waranga Basin, contributing to development and water security in the Loddon and Campaspe River systems as well the cities of Bendigo and Ballarat. Usually, only a quarter of the flow from the upper Goulburn is allowed to flow down its original river course, the rest is diverted via channels. Given how seasonal and unreliable our rainfall is in Australia, it would not be possible to grow enough food for our population, let alone export, without such schemes and the visionaries that created them. They do contribute to problems in the Murray Darling Basin, such as salinity caused by over-irrigating, the deteriorating condition of redgum forests, wetlands and the soil in seasonal floodplains by decreasing the frequency and size of floods in those areas. The lack of flow in rivers within the Murray Darling Basin caused the Murray mouth to be blocked for many years and water in the Coorong to be much saltier than the sea. Water birds dependent on these wetlands to feed their young and fuel their global migration began to die out and water quality and security in the lower catchment towns (including the Capital city of South Australia: Adelaide) began to suffer. Community concerns and international obligations to the preservation of wildlife forced the Australian government to act, bringing the three state governments together to agree how to better manage their shared water reserves: and so the Murray Darling Basin Plan was born. The arrogant and ignorant attitude of 'If it flows past my door I can use it and what happens downstream is no concern of mine' was no longer allowed. Catchment Management Authorities now cooperate to ensure that the environment is not forgotten and that water is managed following strategies that benefit the whole basin. On my paddle, this meant that I had an environmental flow, more water than usual was being released, promoting native fish breeding and delivering water downstream at the same time. It also improved the current, making my journey easier.

|In the company of a Goulburn Murray Water staff member, we were able to drive down to the boat ramp below the weir. Although you can see three gates open here, in winter, often only one will be.|

Downstream of the Goulburn Weir, the river changes remarkably, the banks are covered in native grasses and the bush looks healthy. All of the vegetation is native; there is no sign of the willows so dominant above the weir. A large male eastern grey kangaroo watched me as I paddled past. The surface of the water was so covered by the ripples left by moving water skaters looking for their insect prey, that it looked like it was raining. The sound of water cascading from the weir behind me ebbs and wanes. Sometimes it is quite loud and I caught myself having to check behind, unable to be sure there really was not a great wave about to engulf me.
|The lower Goulburn is the section of the river below Goulburn Weir at Nagambie. The river slows and the banks grow higher. Its colour changes to the green brown of many of Australia's inland rivers. It is no longer the mountain stream that it was above Seymour. It is a though the Goulburn has grown up. Map source: Wikipedia. See also DEPI for information on river conditions.|
|This section of the Goulburn River is lined with River Red Gums and is an important wildlife corridor linking the mountains of the Great Dividing Range to the Murray River. The picturesque river has narrow strips of vegetation along its meandering banks, with the adjoining River Red Gum forests and woodlands providing a striking contrast to the farmland which was so often a feature along the upper Goulburn. See Park Web|
|A few kilometres below the weir I came across this remarkable brick water tower, which I believe belongs to a local winery.|
|The reason why the current is much slower in the Lower Goulburn than in its upper stretches is because the rate of fall is much less: the Goulburn drops most dramatically (300 m) in the first 200 km: in its last 250 km, it only drops around 50 m. Reach report|

There are many camping sites around Murchison. It was Friday afternoon as I passed through and the weather was hot. Everyone who could be was down at the river. Some had come down to swim, others had set up for the weekend and had just thrown in their first lines, hoping to be able to catch something for the evening meal. I have seldom seen so many good camping sites so close together. i later heard that people come from a long way away to camp here.
I continued on, hoping to make it to Toolamba, but with thunder signalling the threat of an approaching storm, my radio informing me of heavy downpours in the region and tiredness from a long day on the water, I pulled in for the night 4 km upstream from Old Toolamba, at a beach campsite. Tomorrow I will pass through Mooropna and Shepparton and will be accompanied by Barry Bell, a fellow paddler and friend, who drove along the bush tracks and shared a beer with me last night.
