The present study examined the behavior of a reservoir located on subtropical latitude (Dona Francisca reservoir).
The limnological variables measured were dissolved oxygen, temperature, pH and electric conductivity.
Measurements were taken quarterly at different sampling sites along the reservoir.
The results indicated the formation of longitudinal zones regarding circulation patterns and stratification, beyond the influence from the water masses of the main tributary.
The vertical profiles were...
