[RegCNET] Bug in the interactive lake model

[GIORGI FILIPPO]

Dear MIchael

we are working on reactivating the lake model, also because we need ot for
one of our projects. Hopefully it will be ready soon. Of course we are
working now with version 4, so if you still use V3 which we are not
maintaining any more, you will have to traspose to V3 the fixes in V4.

cheers,   Filippo
