The road bridge across the lake was built before the lake was filled, commenced in 1917, and completed in 1924. It replaced an earlier wooden bridge built in 1889–1891. The bridge was started from both ends, each by the respective state government. However, they did not coordinate their efforts, and the bridge has a dip and a bend in the middle to make the two ends meet.
The Yarrawonga Weir is the farthest downstream obstruction across the Murray that does not have a navigation lock through it. When full, the lake is 124.9 metres (410 ft) above sea level. The weir is 1,992 kilometres (1,238 mi) upriver from the river mouth.
Lake Mulwala is a renowned fishery for the native Murray cod and is one of the few places where this Australian native freshwater fish is still reasonably common.
