LAST UPDATEDTaylors Lake is an off-stream reservoir and a reliable water source for the region. Sitting 20 km south-east of Horsham, it's supplied from upstream storage within the Wimmera-Glenelg headworks. The nearby Potters Creek also serves as a small natural catchment.
The lake has an important role in supplying environmental water to the Wimmera River. It's also very popular with Horsham locals for recreation, especially camping, fishing and water skiing. When other lakes are dry, Taylors Lake will often still have water to enjoy.
Be sure to play it safe around water.
Read our information signage before entering the water.
