datum/unit conversion on a GRID DEM (water table)

The file is a water table that was specifically developed for a different project. I want to use this file for my project but I'm working in UTM. I would like to go from GSC WGS 1984, linear unit = feet to NAD 1983, UTM Zone 13N, linear unit = meters.

If this is possible and someone knows how, please share.

Thanks,
R
