From figure 2 and a principal component analysis (not shown), we can divide the values obtained in complexity categories as follows:  {\bf Very High Complexity} C \in [0.8, 1]. The following variables balance self-organization and emergence: benthic and planktonic{\it pH} ({\it BpH}, {\it PpH}), inflow and outflow ({\it I&O}), and retention time ({\it RT}). It is remarkable that the increasing of the hydrological regime during summer is related in an inverse way with the dissolved oxygen ({\it SO_2}; {\it BO_2}). It means that an increased flow causes oxygen depletion. Benthic Oxygen ({\it BO_2}) and Inflow {\it Ph} ({\it IpH}) show the lowest levels of the category. Between both, there is a negative correlation: a doubling of {\it IpH} is associated with a decline of BO_2 {\it BO_2}  in 40 percent. {\bf High Complexity}C \in [0.6, 0.8). This group includes 11 of the 21 variables and involves a high {\it E} and a low {\it S}. These 11 variables that showed more chaotic than ordered states are highly influenced by the solar radiation that defines the winter and summer seasons, as well as the hydrological cycle. These variables were: Oxygen ({\it PO_2}, {\it SO_2}); surface, planktonic and benthic temperature ({\it ST}, {\it PT}, {\it BT}); conductivity ({\it ICd}, {\it PCd}, {\it BCd}); planktonic and benthic light ({\it PL},{\it BL}); and evaporation ({\it Ev}).
