The Science Behind It
The evidence for restoration
The Evidence Room
Undeniable authority and urgency
The case for restoring Lake Pedder rests on decades of ecological, hydrological, and engineering research. Below are the key findings that make restoration not only possible, but responsible.
Intact
The Beach Survives
Sonar and core sampling of the impoundment floor confirm the original quartz-sand beach lies beneath the reservoir, largely undisturbed beneath a thin layer of silt. The physical foundation of the original ecosystem is still there.
Feasible
Hydrology is Reversible
The impoundment is managed by a series of dams and canals. Engineering assessments confirm that water levels can be incrementally lowered to re-expose the original lake bed. The infrastructure to achieve this already exists.
Proven
Ecological Rewilding
Global precedent shows that degraded wetlands can recover with remarkable speed once hydrological conditions are restored. Endemic flora and fauna would recolonise from surrounding wilderness areas.
Positive
Carbon & Climate
Restoring the shallow lake and wetland system would sequester significant carbon, improve biodiversity outcomes, and enhance the resilience of the Southwest wilderness to climate change.
