The retention potential may be very low for some reservoirs, depending mainly on factors such as dissolved oxygen concentration, light penetration, water velocity, stratification, height of water outlet, and
epilimnion and hypolimnion depths.
The ALMS collected continuous in situ time series of key climatological, hydrological, chemical, and biological parameters during both open-water and under-ice seasons and in both the
epilimnion and hypolimnion (68[degrees]31'37" N; 133[degrees]30'48" W).
However, during the study period there were occasions of partial mixing in the
epilimnion, especially in January and February, but also in July and August, when the surface waters cooled down by 1 [degrees]C to 1.5 [degrees]C.
Fetch determines how deeply wind-driven currents can mix the upper layer of the water column, or
epilimnion.
It is revealed in Figure 15 that [Re.sup.1/2.sub.x][C.sub.fx] increases with at
epilimnion stage which is known as the highest and warmest layer ([S.sub.t] = 0).
The thermocline layer observed at 3 m to 7 m separates the
epilimnion ([approximately equal to] 30.5[degrees]C) and hypolimnion ([approximately equal to] 25.5[degrees]C) at Station 2.

epilimnion of southeastern Quebec lakes.
En la LR las diferencias entre el
epilimnion y el hipolimnion se hicieron cada vez menores hasta la ruptura de la estratificacion termica durante el otono con la mezcla completa de la columna de agua, lo que genero que las condiciones fisicas y quimicas del lago fueran similares a las determinadas en LM y LTP, durante este periodo.

The high surface temperatures and the presence of a thermocline prevent mixing between the hypolimnion and
epilimnion, leading to differences in parameters such as phytoplankton, pH and DO (Gu and Stefan, 1995).
