Big Sandy River of Kentucky Lake (TN)
The area in color on the left is the portion of the Big Sandy River
and Eagle Creek Embayments that have been re-mapped.
NEW depth data was collected from September - December of 2001.
The new maps extend from the junction of the Big Sandy River and Tennessee
River to just north of a major power line crossing the bay to the south.
The high resolution imagery for Big Sandy is based on over 185,000 depth
readings covering more than 2400 acres. This is by far the largest area
re-surveyed by Kentucky HydroGrafx to date.
The bay is divided into 8 sections. Topographic images for each section
contain a contour interval of 1.0 or 2.0 ft.
As you see here, the images are actually a hybrid image including the
brand new data, plus background imagery of Charts 113 & 104. Also
included in the background is aerial photography to help get oriented
with real world features.
Topographic images on CD each contain a latitude and longitude grid and
coordinates for easy calibration with GPS mapping software.
This is a sample from Section 1 just below the center of that section.
The image here is somewhat distorted by compression to minimize download
time for this page. The image you receive has no distortion.
Latitude/Longitude grid lines are provide on the topo maps for easy
calibration with GPS mapping software.
The contour interval is 1.0 foot below the white contour line and 2.0
feet above the same white line. This is done to reduce stacked contours
on steep slopes but showing as much detail as possible on more gentle
Hundreds of spot elevations are included on all section maps for easy
reference. If you know the current lake elevation, then water depth can
be easily calculated.
The next step in 3d viewing has been included in all
high resolution Big Sandy Images
An improved 3d imaging technique has been used to produce the Big Sandy
The same high resolution topographic images have been "draped"
over the digital elevation model created by Kentucky HydroGrafx. The shading
effect of artificial sunlight on the model helps our brain comprehend
the elevation changes. The summer pool level of 359ft is represented on
non-surveyed edges as the blue/green color you see here.

to the home page and brush your mouse pointer across the "3d Lake
Terrain Imaging" button.

A DEMO version of OziExplorer GPS Mapping software is provided on disk
to get you started with precision fishing. The HydroGrafx images work
flawlessly with this version.
