Dunstan Rohe
The Dunstan Rohe runs from the outlets of lakes Wānaka, Whakatipu and Hāwea down to the Clyde dam and includes the Kawarau, Nevis, Shotover, Upper Clutha/Mata-au, Hawea, Cardrona, Arrow, and Lindis Rivers.
These catchments contain diverse landforms from the rugged Kawarau gorge, tracts of native bush in the remote Shotover catchment, to extensive agriculture and fruit-growing areas. Cromwell, south of Lake Dunstan, is the largest urban centre.
Water quality is generally very good.
Monitoring has found degrading trends particularly where there is pressure on water quality in drier catchments that have high water use or high population growths rates.
The outflows of Lakes Wānaka and Whakatipu are unregulated. However, Hawea Dam controls the outflow of Lake Hawea. This rohe also includes Lake Dunstan, a run of river hydro lake created by the Clyde Dam and Lake Hayes.
