Hydrology relates to the study of the properties, distribution, and effects of water on the earth’s surface, in the soil and underlying rocks and in the atmosphere. Water plays an important role in the formation and development of caves. Your Margaret River region’s caves are formed through the action of water dissolving through young (soft and porous) limestone.
Rainfall and land use dramatically affect the characteristics of our caves. Mammoth Cave has a seasonal stream dependant on winter rains and Jewel Cave unfortunately lost its underground lake 30 years ago. The iconic Lake Cave is fed by an underground spring, and has recently experienced fluctuating water levels. The Lake Cave Eco-Hydrology Recovery Project commenced in 2010.
The project aims to:
- Sustain the current water levels in Lake Cave
- Assess the condition of the stygofauna (threatened groundwater-dependent invertebrate species) community, and;
- Gain an understanding of the Lake Cave catchment system.
The MRBTA is committed to implementing sustainable tourism practices to balance the impact on the environment while meeting present and future needs. To ensure protection of the caves, it is important to protect the entire water catchment
