hello
I simulate the climte effect of the Poyang  lake ,so I must use the lakemodel.
I set the lake mod 1, after ./regcm.x
and appear the following  :

PGFIO-F-209/formatted read/unit=40/'OLD' specified for file which does not exist .
 In source file initlk.f, at line number 36

then  stop
what is the problem?
I look for the original code
I do not kown whether there is change.
