However, these DSi fuxes in southern lakes are little known. This work evaluated the spatio-temporal variation and the main factors that afect DSi dynamics and retention in a temperate groundwater fow-through shallow lake in Argentina. Water samples from streams, the lake, and groundwater were collected from Los Padres Lake Watershed for DSi determination. DSi retention was calculated through a mass balance approach. The BSi pool from macrophytes was quantifed using biomass, BSi production, and satellite images. The phytoplankton community was described by chlorophyll content, species quantifcation, and alpha diversity metrics. The contribution of Si-enriched water from groundwatere EN  ESTE ARTICULO  ESTOY EN AGRADECIMIENTOS
