Lake Esmond (Ballarat)

Moderate risk: Deep cold untreated water

Lake depth exceeds 2 m and the water remains cold year-round; untreated natural water may contain bacteria.

Low risk: Stormwater runoff after rain

Small urban stormwater drains enter the lake on the southern side; avoid swimming for 48 hours after heavy rainfall due to potential poorer water quality.

Low risk: Poor visibility near shore

Clay bottom stirs up easily, reducing underwater visibility to near zero when disturbed — hazardous for snorkelers unfamiliar with the bottom.

Low risk: Submerged vegetation and reeds

Reeds line much of the shoreline; entry is restricted to cleared gaps. Unseen reeds and silt can entangle swimmers.

Low risk: Slippery clay bottom

The clay lakebed becomes very slippery and stirs up sediment, reducing visibility near the shore on entry.

Low risk: Reeds restricting entry

Thick reeds line much of the shore; entry is limited to a few cleared gaps, mainly at the eastern end.
