Lolworth Creek Wetlands

From Dry Tropics Wiki
Jump to: navigation, search


This sub-division is based on the Great Basalt Wall, a major basalt feature with numerous springs emanating from many locations. These springs drive the permanency or semi-permanency of many major in-channel waterbodies and large off-channel lakes and swamps. Fletcher Creek on the north side of the basalt wall, and Toomba Creek on the south side, have near-permanent surface flow. Lolworth Creek contains several deepwater lagoons. All systems here either have clear water or relatively so. Several of the lakes are filled by catchment surface runoff rather than springwater. Condition of all waterbodies is generally considered to be relatively good.
