Hagg Lake Bathymetry

OK, so here's something I found the other day. GIS information which is supposed to include not only the topography around Hagg lake but also the bathymetry under the water.

GIS Coverage of Scoggins Creek Drainage and Henry Hagg Lake Bathymetry

The data is only 20m so it's not the most incredibly, but something is better than nothing. Now if someone with the appropriate knowledge of GIS would be willing to take that data and generate some high resolution images of the lake I'd greatly appreciate it :-).

Some quick calculations in Google Earth show Hagg lake to be about 4km x 4.5km, 20m resolution says that's about 200x225, from which nyquist might suggest 400x450. OK, I hope my calculations are right.
