Bet Bet Creek in west Victoria starts below Ben Major, Victoria (west of Lexton) at an elevation of 479m and ends at an elevation of 165m flowing into the Loddon River at the Laanecoorie Reservoir.

Bung Bong, Victoria is located at the boundary of the Pyrenees Shire and the Shire of Central Goldfields which are separated by the Bet Bet Creek.

Stored salts have been liberated, predominantly due to erosion, into the upper tributaries of the catchment and these have accumulated lower down in the creek.

This has degraded the water quality flowing into the Laanecoorie Reservoir.

Early gold mining has produced some degradation of the creek environment.
