Hello,
please check following things:
1) water level at seed point/area is above terrain (provided DEM);
2) seed point/area is located within current computational region
(just run g.region rast=my_dem before r.lake);
3) seed point/area has values > 0 (quirk of current implementation).
Good luck!
Maris.
PS. 3rd check probably could be eliminated by slight alteration of
r.lake code. Just a note to myself

HI! ALL
I have been trying to generate a lake feature from dem and seed raster files
using r.lake, this is information below.
The areas are not created as values can be seen below.
