Lake Barrine is a freshwater lake situated on the eastern parts of Atherton Tableland in Far North Queensland, Australia, close to Lake Eacham. The lake and surrounds are protected within the Crater Lakes National Park and are accessible via the Gillies Highway. Lake Barrine was formed over 17, 000 years ago when a large volcano erupted, leaving a crater that over time filled up with water to create a lake. The crater or maar was formed as a result of a series of volcanic explosions. These explosions were caused by the hot molten rock coming into contact with groundwater. This caused a build-up of steam, gases and pressure which blasted the central core from the volcano. This massive explosion left a huge crater, which filled with rainwater to create Lake Barrine. Local Aboriginals called the lake Barany. The largest of the natural volcanic lakes in the area, Lake Barrine is 730 m above sea level. It is about 1 km in diameter, with a shoreline of almost 4.5 km and an average depth of 65 m. No streams or springs feed the crystal clear lake; it is filled only by rainwater. During the wet season a small creek flows out of the lake. It joins Toohey Creek which is a tributary of the Mulgrave River. There are walking tracks around the lake and tour operators offer cruises on the lake. Facilities at the lake include picnic grounds, a kiosk and a pre-war tea house which was built in 1926. Visitors may also swim in the lake and partake in birdwatching. Camping and domestic animals are prohibited near the lake. The surrounding rainforest contains giant kauri (Agathis microstachya), Red cedar trees and flowering umbrella trees (Schefflera actinophylla). Wildlife common in the area include eastern water dragons, giant eels, sawshell turtles, scrub pythons (Morelia kinghorni), Pied Cormorants, black ducks, plumed whistling ducks, black coot, whistling kites, brahminy kites, black kites, white breasted Sea eagles and dusky moorhens.
