This hydrologic behavior influences the physiochemical subsystem of the lake.  Table ** and Figure ** show the variables and daily data we obtained from the Arctic lake simulation.      \subsection{North1 Lake}  The named in following: North1 lake is a lowland eutrophic lake, located in a warm North-Temperate climate (mean Tº of 14ºC). Their primary production expressed in mg/m3 of chlorophyll is around 6.3-19.2. There are four seasons in a year, winter, spring, summer and autumn. In summer, the flow variations (Inflow and outflow fall to 3.5 from 25.2 and retention time increases to 100 days), the lack are lack or absence of seasonal wind and high temperatures (24ºC), causes the water column thermostratification. Stratification is expressed in generation of two layers. At the border of these layers, temperature changes dramatically (24ºC Surface to 20.6 in Planktonic layer, to 17.3 in Benthic layer). Water above and below of thermocline do not mix. The warmer water is near the surface and denser water is near the bottom. In winter, there is no ice covering in the surface. Opposite to the summer when the flow is minimum, in spring and autumn the water column overturns (Retention Time of 14 days and Zone Mixing of 100%), causing increases in conductivity.

\subsection{North2 Lake}  North 2 lakes corresponds with a highland mesotrophic ecosystem in a cool North-Temperate climate (Mean 5.3ºC). Levels of chlorophyll are between 2.2.-6.2 mg/m3. The surface is covered with ice in winter (end of November, December, January and early February). Ice covering forms a barrier to the wind which minimizes losses of water evaporation while the bottom of the lake remains unfrozen. The water column does not thermostratified and is permanently well mixed whit levels of 50% in summer and 90% in winter. The maximum flows are in spring and autumn (9.6) with minimum flow in summer(0.6). Evaporation is reduced because their water is more or less cold and vapour-pressure gradients are no large (mean of 9,262). Retention Time is maximum in summer with 100 days. Oxygen concentration is upper to 10 mg/lt in the three layers. pH mean values are around 7 to 7.3, but it moves in a range of 6.7 to 7.8 from the surface to bottom.     Variables correlations are more seasonal than the N1. It means the period of winter is related with high retention time, higher pH and winter with the higher levels of oxygen, inflow and outflow and oxygen. However, there is a more strong correlation of benthic and sediment Oxygen.     \subsection{Tropical Lake}
