Figure 55. Cumbulla (C) land system. Alluvial plains in part actively forming and largely
flooded in the wet season; texture-contrast soils; paperbark woodland (Galloway et al.
1970). ....................................................................................................................... 145
Figure 56. Land use map of the Mitchell catchment showing a) operating mines, abandoned
mines, mine claims, proposed mines, b) distribution of major alluvial gullies, c) major
paved and unpaved roads, d) existing and proposed water resource development, e)
agricultural development near Dimbulah (green outline). Note the relatively sparse
development in and around Oriners and Sefton Stations. ......................................... 148
Figure 57. Minimum flood inundation frequency data for Oriners and Sefton Stations and part
of the Mitchell fluvial megafan (MODIS satellite imagery, number of times inundated
between 2003 and 2009; Ward et al. 2012). Major permanent water body locations and
typical dry-season water clarity estimates from Landsat satellite data (1986 and 2005)
are also shown (Lymburner and Burrows 2008), as are the locations of smaller
intermittent palustrine wetlands are also shown in black (Queensland Department of
Natural Resources (QDERM) 2010).......................................................................... 149

Figure 59.Photographs of a mound spring on western Oriners Station with a) water seeping
to the surface, b) fluid muds oozing to the surface under pressure, c) the pebble lags of
gravel and ferricrete nodules on the spring surface, and d) sheet wash deposit on top
of the spring following wet season rain-fall runoff or groundwater discharge. ............ 153
Figure 60. False colour satellite image (ASTER) of the river segment and landscape
surrounding Oriners Station and Eight Mile Creek. Note bright red colour is riparian
vegetation (mainly Melaleuca spp.) growing along Eight Mile Creek. Inset box refers to
air photographs in Figure 64 and Figure 65. ............................................................. 154
Figure 61. Digital elevation model of the river segment and landscape surrounding Oriners
Station and Eight Mile Creek using the 30m pixel data from the Shuttle Radar
Topography Mission (SRTM 2000). Inset box refers to air photographs in Figure 64 and
Figure 65. Cross-section lines refer to data in Figure 62. .......................................... 155
Figure 62. Elevation cross-sections across the Eight Mile Creek Valley at Oriners, derived
from the Shuttle Radar Topography Mission 30m pixel digital elevation model (SRTM
2000). Cross-section locations are mapped in Figure 61. Note that 2 to 5 m fluctuations
in elevation could be errors from vegetation artefacts in the data. ............................. 155
Figure 63. Longitudinal profile of the Eight Mile Creek Valley from the confluence of Crosbie
Creek to the headwaters derived from the Shuttle Radar Topography Mission 30m pixel
digital elevation model (SRTM 2000). The Oriners segment of Eight Mile Creek is also
mapped in Figure 61. ................................................................................................ 156

Figure 65. 2004 Aerial Photograph of the Eight Mile Creek reach near Oriners Station and
Lagoon, showing existing (pre-2004) and new road (2010) infrastructure, air strip and
gully erosion problem areas. See Figure 68 for detail of inset box. ........................... 158
Figure 66. Ground photos during July 2011 of a) Eight Mile Creek looking upstream near the
main anabranch bifurcation that feeds Oriners Lagoon, note major sand bar deposits
that influence channel divergence and anabranching, b) Eight Mile Creek looking
upstream below the main anabranch bifurcation that feeds Oriners Lagoon, c) the main
anabranch channel looking downstream that feeds Oriners Lagoon, and d) the smaller,
most upstream, anabranch channel looking downstream that feeds Oriners Lagoon.159
