What was once a deep hole left behind by coal mining is now a destination for swimming, boating, camping and water sports.

Lake Kepwari, near Collie in Western Australia, began as the Western 5B mine void at a former open-cut coal operation.
asserted
Kepwari → begin → operation
After the mine closed in 1997, the site was progressively transformed into an artificial lake.
asserted
site → close → lake
Over time, water filled the void, creating a large recreational water body that eventually became part of efforts to diversify Collie’s tourism opportunities.
asserted
that → fill → opportunities
By late 2020, Lake Kepwari had opened to visitors with new infrastructure designed to turn the former mine site into a water-based recreation hub, according to the Western Australian Government.
uncertain
Kepwari → open → Government
From coal mine to artificial lake
Lake Kepwari is located about 13 kilometres southeast of the Collie townsite and covers about 103 hectares.
asserted
Kepwari → locate → hectares
The Western Australian Government’s Upper Collie Water Management Plan issue-scoping report identifies it as an artificial lake created from the Western 5B mine void.
asserted
report → scope → void
The former Wesfarmers Premier Coal mine site closed in 1997.
asserted
site → close → 1997
The transformation was part of a broader approach to rehabilitating former mine areas in the Collie region.
asserted
transformation → rehabilitate → region
Open-cut coal mining had created numerous large voids across the Collie Coal Basin.
asserted
mining → create → Basin
As mining ceased, some of these depressions filled with water and became mine lakes.
asserted
some → cease → water
The government report noted that several former mine voids, including Lake Kepwari, Stockton Lake and Black Diamond A, had already become or were being developed as recreational lakes.
asserted
voids → note → lakes
Lake Kepwari was planned for uses that were very different from its industrial past.
asserted
that → plan → past
These included picnicking, camping and water sports such as water skiing.
asserted
These → include → skiing
The development was guided by the South West Development Commission and the Lake Kepwari Working Group, which included government, industry, local community and recreation representatives.
asserted
which → guide → representatives
How the mine void filled with water
Filling such a large former mine void was not simply a matter of waiting for rain.
asserted
Filling → fill → rain
The Western Australian Government reported in 2008 that Wesfarmers Premier Coal had rehabilitated the mining void and obtained a licence from the Department of Water to divert water from the Collie River South Branch to help fill the lake.
asserted
Coal → report → lake
The government statement said Lake Kepwari held about 30 gigalitres of water, equivalent to about 30 billion litres.
asserted
Kepwari → say → litres
It described the lake as almost two kilometres long, about one kilometre wide and up to 70 metres deep.
asserted
It → describe → lake
The earlier water-management report also noted that the lake could require supplementation while groundwater levels in the surrounding Collie Coal Basin recovered.
uncertain
levels → note → Basin
Water quality presented another challenge during the development phase.
asserted
quality → present → phase
Stakeholders raised concerns about acidity in the lake, with reduced acidity identified as necessary before the site could safely operate as a public recreation venue.
uncertain
site → raise → venue
These issues illustrate one of the challenges involved in converting a former mine into a recreational lake.
asserted
issues → illustrate → lake
Creating a large body of water is only part of the process; its chemistry, stability, access and surrounding infrastructure also have to be considered before people can safely use it.
asserted
people → create → it
A new role for a former mining landscape
The idea behind Lake Kepwari was not limited to rehabilitating a mine site.
asserted
idea → limit → site
It was also connected to the changing recreational and tourism landscape around Collie.
asserted
It → connect → Collie
The 2007 government water-management report identified Lake Kepwari as a feature with significant social value.
asserted
report → identify → value
Stakeholders saw potential in the site for recreation and tourism, particularly water skiing.
asserted
Stakeholders → see → recreation
The report noted that many participants viewed the development of the lake as an innovative way of creating a water-based recreation venue from an old mine void.
asserted
participants → note → void
That vision eventually became part of a larger investment in Collie’s parks, forests and outdoor recreation facilities.
asserted
vision → become → parks
In 2017, the Western Australian Government committed $23.3 million to infrastructure for parks and forests in the Collie region, including $5.2 million for new campgrounds and boating facilities at Lake Kepwari.
asserted
Government → commit → Kepwari
Opening as a recreation destination
The transformation reached a major milestone in late 2020.
asserted
transformation → open → 2020
According to the Department of Biodiversity, Conservation and Attractions, Lake Kepwari opened for visitors with facilities including camping areas, a boat ramp, floating jetty, picnic shelters and parking.
uncertain
Kepwari → accord → areas
The lake now offers activities including swimming, boating, water skiing, camping and picnicking.
asserted
lake → offer → swimming
Its development has given a former industrial landscape a completely different purpose, while adding another attraction to the Collie region’s growing outdoor recreation offering.
asserted
development → give → offering
From industrial void to tourism asset
Lake Kepwari represents a striking example of how former mining landscapes can be repurposed after extraction ends.
asserted
extraction → represent → example
The site did not simply disappear when coal mining stopped; instead, the mine void became the foundation for a new water landscape.
asserted
void → disappear → landscape
Its transformation also reflects a broader challenge facing resource-dependent communities.
asserted
transformation → reflect → communities
As mining landscapes change, former industrial sites can potentially take on new roles in recreation, tourism and community life.
asserted
sites → change → recreation
In Collie, Lake Kepwari became one part of that transition.
asserted
Kepwari → become → transition
