Clarke River Wetlands
This is a very large but dry sub-division. The Clarke River itself is a largely dry sandy, seasonal river channel. However, the headwaters of this system and those of several of the key tributaries begin in basalt country, and thus contain significant permanent, clear-water waterbodies fed by basalt springs, or in the case of the Broken River: limestone. Condition of the spring-fed waterholes is generally good, though some of the tributaries are poorly known ecologically.
