Sunrise at Balonne River

Balonne & Culgoa Rivers

11 to 22 March 2020

Flat, dry and hot... you will actually be "out the back o’Bourke" in some of the most remote parts of north western NSW.

The Balonne River starts where the Condamine and Dogwood rivers join around halfway through the most remote section of the section between the small towns of Condamine Township and Surat (~200 km) in QLD; that is in turn halfway between Chinchilla and St George (475 km).

The Culgoa River starts about a day's paddle from St George as a distributary of the Balonne that channels off almost all of the water under non-flood flow. The Balonne technically finishes downstream at the Ballandool - Bokhara split, though often this section is known as the Balonne Minor River. You cross the border while paddling the Culgoa River.

The Barwon and Culgoa Rivers meet to form the official starting point of the Darling River.

    Balonne River starts where the Condamine and Dogwood rivers join.

    River Red Gum timber survives for decades in the water so old fallen trees are common all throughout the Murray Darling Basin.

    I paddled this section with a falling river of just 4.45 m and 95 ML/day. There were a small number of particularly bad sections of fallen trees between Chinchilla and Surat. The few kms by the confluence of Dogwood Ck was one of these.

    Surat

    Wide slow flowing river lined by gum trees
    Date 11 March 2020
    Distance between locations 103.3 km Elevation 241 m Slope 0.19‰
    Coordinates 27° 8' 60.0" S, 149° 4' 23.5" E

    Flood: minor: 4.8 m, moderate: 6.8 m, major: 8.8 m
    Flow: no flow: 2.88 m

    Surat is a small country town with a general store.

    The Balonne River is generally deep and wide with some narrower sections on good flows before a decent day's paddle along Lake Kajarabie. On a low flow, expect to fight through a significant number of log jams.

    When Lake Kajarabie is filled, the waters extend a long way up to around Wycombe. Below the dam there are some fairly shallow rocky sections just before the flat waters created from St George Weir. This would likely be impassible with a very low flow.

    In 2020, I was dropped off late and bivvyed by the river before leaving early in the morning. River height of 3.7 m with a flow of 34 Cumecs.

    In 2021, I paddled past on a much lower flow. River height of 3 m with a flow of 2.5 Cumecs. I portaged over numerous log jams, as well as a 7 km portage along the road from the dam down to the Carnarvon Hwy as there was no water being released.

    Flow: no flow: 1 m

    Make good use of the two supermarkets in town, a Foodworks and IGA. It is a long way to Bourke! Other possible stores are a long way from the river and could be closed.

    The section below the Dam was the shallowest seen on the decient flows I had on my first trip and there was no water being released from the dam at all on my second trip. I was forced into a 7 km portage to make it to the weir waters above St George.

    I made a quick stop for supplies, though I only brought a couple days extra food and some fruit. I'm carrying 35 L water for the next leg.

    I left St George with a river height of 3.4 m with a flow of 133 Cumecs.

    Culgoa River Head

    Flooded river with trees
    Date 14 March 2020
    Distance between locations 74 km Elevation 177 m Slope 0.25‰
    Coordinates 28° 25' 44.0" S, 148° 16' 15.6" E
    Gauge: Whyenbah, BoM; QLD WMIP
    Catchment: 79,330 sq km
    Flood: minor: 3.5 m, moderate: 5 m, major: 5.8 m
    Flow: no flow: 1.9 m

    What way to go????

    I had initially thought the Bokhara River was the best choice as it has multiple small towns that could be used for supplies, but the Culgoa River appears to have the best overall flow when there is water. The Bokhara River appears to be mostly dry outside of flood events.

    Culgoa River is 489 km long and rejoins the Barwon River to form the Darling River. It did have a store about half way at Weilmoringle but this is now closed. Even after joining the Darling River you still have 108 km to go to get to Bourke. This means that you will be faced with a 600 km leg without supplies unless you organise a food drop somewhere along the way.

    The Birrie River flows from the Bokhara River back into the Culgoa River and the fourth major river distributary of the Balonne River, the Narran River, flows into the ephemeral (temporary) and endorheic (closed, no outlet rivers) Narran Lake.

    In a pinch you could walk over to one of the towns along the Bokhara River. If you are lucky you may even have some luck with a passing car.

    Dirranbandi

    Coordinates 28° 35' 59.3" S, 148° 12' 31.3" E
    Population 640 General Store
    Foodworks in town. This is 13.5 km along Bollon Dirranbandi Rd if taking the Culgoa River, about 33 km from the rivers head.
    Hebel, QLD
    Elevation 153 m
    Coordinates 28° 58' 9.5" S, 147° 47' 49.2" E
    Population 149 General Store

    Small store. ~100 km downstream from Dirranbandi if on the Bokhara River (a super rough estimate). This is 28 km along Woolerbilla Rd if taking the Culgoa River, about 123 km from the rivers head.

    Both Hebel and Dirranbandi are on the St George to Lightning Ridge bus route.

    Goodooga, NSW
    Elevation 142 m
    Coordinates 29° 6' 40.7" S, 147° 26' 52.4" E
    Population 247 General Store
    ~50 km downstream from Hebel if on the Bokhara River (a super rough estimate). This is 15 km along Goodooga Brenda Rd if taking the Culgoa River, about 190 km from the rivers head.

    Gauges at the border, or see the BoM Northwest Rainfall and River Conditions Map.

    Flow from the Beardmore Dam peaked slightly overnight and this ensured a great flow down one of the most remote sections of the river.

    Weilmoringle

    River in flood, banks overflowing with no clear way on what way to go
    Date 19 March 2020
    Distance between locations 280 km Elevation 125 m Slope 0.19‰
    Coordinates 29° 14' 55.7" S, 146° 55' 30.4" E
    Population 80
    Gauge: Weilmoringle, BoM; WaterNSW
    Flood: minor: 5.2 m, major: 5.8 m
    Flow: no flow: 1.7 m

    Tiny indigenous community in the middle of nowhere! The Post Office / general store has been closed from about 2018, so expect up to a 600 km leg without supplies unless you organise a food drop somewhere.

    At Weilmoringle, the river was classed as being in moderate flood with a height of 5.4 m with a flow of 83 Cumecs. I could paddle across to the flood banks beside the town where I stopped to ask for water from one of the locals.

    It was cool hanging for 15 to 30 minutes with Luke who got some additional water for me, the only social interaction I would have in nearly 600 km!

    Darling River Head

    First time around, almost all of the flow was being generated from the flow out of the Culgoa floodplains. River height of 5.2 m with a flow of 108 Cumecs at Bourke.

    On my return trip, the river was in minor flood from the Barwon River. River height of 9.4 m with a flow of 30,000 ML/day at Bourke.

    Paddling both flows was pleasant, the main difference was one didn't have to climb the banks much to camp!
