accodrding to "Arc Hydro Tools Tutorial (Version 2.0 - October 2011)" to process the "Adjust Flow Direction in Lakes" function I need to:
Confirm that the input for Flow Direction Grid is ???FdrSink???, Lake Polygon a lake polygon feature class (e.g. NHDWaterbody) and Stream a line feature class (e.g. NHDFlowline). The output is the Bowled Flow Direction Grid, named by default ???BowlFdr???. This default name can be overwritten.

but it can`t be done because this function requires grid data as initial to stream (grid?). So, I don`t know how to perform this tutorial further.
Best regards.
