DESCRIPTION:Understanding how large lakes interact with multilayer aquifers
  is crucial for managing water resources\, especially where groundwater an
 d surface water are closely connected. These interactions\, found in many 
 regions worldwide\, are shaped by complex geological formations and dynami
 c groundwater flows. Investigating them requires a multidisciplinary appro
 ach that integrates (i) detailed 3D geological modeling\, (ii) hydraulic c
 haracterization of the subsurface\, and (iii) natural tracers to track wat
 er (and groundwater) movements and refine hydrogeological processes. This 
 study examines the connection between Garda Lake and the surrounding Preal
 ps and moraine-alluvial aquifers\, a essential water reservoir for norther
 n Italy. Spanning the provinces of Brescia\, Mantova\, and Verona\, this a
 rea plays a key role in recharging the Po Basin aquifer system\, making gr
 oundwater monitoring and protection necessary. To explore these dynamics\,
  a hydrogeological conceptual model has been developed using geological su
 rveys\, official maps\, and water well stratigraphy\, supported by isotopi
 c and microbiological tracer analysis. The results confirm a strong hydrau
 lic link between the lake and aquifers. The moraine aquifer\, composed of 
 highly permeable sediments\, is directly connected to the lake bottom and 
 banks\, allowing continuous water exchange. Below it\, the alluvial multil
 ayer aquifer\, with alternating coarse and fine sediments\, also interacts
  with the lake. These aquifers\, in turn\, connect to the fractured Prealp
 s formations\, forming a continuous hydrogeological system at the regional
  scale. By integrating geological\, hydraulic\, and tracer-based analyses\
 , this study provides new insights into lake-aquifer interactions in compl
 ex settings. Beyond its relevance for the Po Plain\, the approach offers a
  valuable framework for managing groundwater in similar regions worldwide\
 , where lakes and aquifer plays fundamental function in the storage of thi
 s vital resource.
