[RegCNET] Bug in the interactive lake model

[Michael Notaro]

To the RegCM3 developers,

It seems that the interactive lake module doesn't work
correctly in either serial or parallel mode.  In both
cases, the precipitation values become zero in the lake subroutines
and there is no snow on ice given the lack of precipitation.  
Could you developers of the model please comment on the problems 
of the lake module and how to resolve these issues?  To my 
understanding, these issues continue not just in version 3 but 
were not resolved in version 4 either.  

Thanks,
Michael
