Ewen Maddock dam is located on the Sunshine Coast about 5km south east of Mooloolah. It is built across Addlington Creek, has a surface area of 370 hectares, holds 16 700 ML of water and has an average depth of 4.5 meters. The dam is named after an early pioneer of Mooloolah.
Where there’s water, there’s fishing and this dam is no exception. It is stocked with Australian Bass, Yellowbelly, Mary River Cod and Saratoga. Fishing is restricted to bank angling or from non-motorised vessels.
Propellor driven vessels are prohibited here because of the weed Cabomba. The propellors break up the weeds and cause it to spread rapidly. Unfortunately there is no public camping area at the dam. Day visitors are well catered for with picnic tables, toilets and children play ground all situated in the shade. There are various walking and horse riding tracks. Dogs on leads are welcome too.
The boardwalk has a bird watching hide and wetland viewing platform from where you can keep a look out for species such as Magpie Goose, Royal Spoonbill, Sacred Kingfisher and Plumed Whistling Duck. 184 bird species have been recorded in and around the dam.
Adjacent to the dam is an advanced water treatment plant. Construction on the plant started in 2007. It supplies up to 20 megalitres of drinking water to Caloundra per day.
