Map of waterways in the Merri Creek catchmentMerri Creek flows south from the slopes of Pretty Sally, a hill forming part of the Great Dividing Range. It meets the Yarra River in Clifton Hill.

Some of the waterways have been put into pipes and are shown on the map as fine dotted lines. Other sections, particularly where there were swamps that have now been drained, have been turned into channels or drains with few natural features.
