The Lennard River Basin covers an area of 12,520 km2 and extends
about 180 km inland in the Kimberley region of Western Australia.
Average annual rainfall ranges from 600 mm in the south to 900 mm in
the north. Flows generally occur between November and May following
rainfall associated with tropical lows, monsoonal depressions and
summer thunderstorms moving inland from the north. Rugged terrain
characterises the land with high ranges and broad, alluvial plains.
Such contrasting landscapes give rise to spectacular cliffs and gorges,
such as the Windjana Gorge.
The Lennard River drains the inland ranges before undergoing a name
change to the Meda River and flowing across vast alluvial floodplains.
Closer to the coast the Meda River becomes extensively braided and
segmented forming numerous tributaries. Many of these do not make it to
the ocean, instead disappearing into large expanses of tidal flats or
into the deep coastal basin sediments.
Lennard Gorge is one of the lesser visited of the Kimberley gorges.
The gorge has a spectacular waterfall that flows like a torrent early
in the dry season, however the narrow, deep canyons can be experienced
all the year around. It can be a hazardous gorge and extreme care
should be taken when exploring and climbing. At the first of the
gorges, there is a rocky walk down to the top of the gorge and it is
possible to descend to the base of the cliffs. Experienced rock
climbers are able to climb the opposite face of the gorge, it is steep
and ropes are essential. Swimming is possible.
There has been little clearing of native vegetation, however
overgrazing by livestock along river flats has been noted in areas,
particularly along the Meda River. Some mining activities are also
present with dewatering activities discharging to nearby creeks.
