Hi ,I have a set of discreet data points in the form of {x,y,z} coming 
from ground water table heigths at x and y coordinates :

data={{156113.590,154311.950,80.45},{156607.600,154195.130,73.78},{156099.360,
 
153761.530,79.92},{156255.630,154280.390,79.43},{156228.850,154044.480,
       80.57},{156475.940,154114.990,79.46},{156419.110,153998.070,
       79.80},{156135.639,153107.940,80.94},{155494.767,153465.528,
       87.22},{156322.591,154045.299,74.71}}

I know it is a smooth surface with a minimum at the fourth point.

I wish to get Mathematica to reconstruct as well as possible the whole 
surface.
How can I go about this?
