 Avoca River in Charlton |

The Avoca River is a river in the center and northwest of the Australian state of Victoria .
geography
It rises at the foot of Mount Lonarch southwest of the village of the same name and flows 270 km north through the cities of Avoca , Charlton and Quambatook . Although the river valley of the Avoca River is part of the Murray-Darling Basin , but the river flows not into the Murray River . Nowhere is the Avoca River particularly wide, meandering north and finally drying up in the Kerang Lakes , a marshland about 20 km southwest of the Murray River, between Kerang and Swan Hill .

Orography
Although the Avoca River has a considerable catchment area with 14,000 km², a large part of it is in the northern plains, where an average of only 350 mm of rain falls per year and the flow speed of the watercourses is not very high due to the low gradient. The mean annual runoff over the Avoca River of 137 million m³ / a represents only 0.67% of the total runoff from the state of Victoria. Most of the water in the Avoca River comes from the narrow, upper part of the catchment area, where the annual rainfall averages about 600 mm / a and most of the rain falls in winter and spring.
Of all the rivers in the Victorian part of the Murray-Darling Basin, the Avoca River is the most volatile. In wet years the runoff can be up to 10 times higher than in drought years. Usually in summer and autumn the river is no longer a continuous body of water, but rather a series of water holes.
Although the Avoca River is the only significant river in this area, no reservoirs have been built on it, only six weirs of rather local importance.
Since there is often no runoff at all in the dry seasons of summer and autumn, the river is hardly used for land irrigation. If there is a runoff, the Avoca River is usually too salty for irrigation of grain fields, but it can still provide drinking water for sheep and cattle.
