Zambra di Montemagno is not totally intermittent as mapped.  Today it carries water at this point, and fish, but downstream it is dry from -- mostly -- a porous riverbed.  Rain is forecast now but there is a constant supply of water far upstream, if only a trickle in arid summers.  Some upstream botri may dry in summer.

There is an extreme between today, the dry summer a year ago (no rain 03./marzo until 09./settembre) and rainy winter months so the precise start of intermittent will be way off.  But in no way can the entire length of Zambra di Montemagno and its botro tributaries be considered intermittent.

Let the next year weather prove me wrong.
