The 2013 campaign continued the University of Milan’s investigation of the later occupation phases in the basin, datable to the middle Bronze Age.

The excavations concentrated on Sector D (in the territory of Lonato) at the centre of the basin, and Sector E (in the territory of Desenzano), facing towards the north-eastern lake shore.

In Sector D, a cumuliform deposit (US 4016) was excavated that contained a large amount of occupation evidence (pottery fragments from reconstructable vases, faunal remains some of which calcined, concentrations of seeds including cornel and hazelnut), and indirect evidence for the presence of raised dwellings that are typically associated with this type of material.
In fact, the well-preserved remains of in situ palafitte structures have been found in sector D, and it is hoped that dendrochronology will help to provide an absolute date for the complex.
The vessel forms were attributed to the Middle Bronze II A or the Middle Bronze I, given the presence of T-shaped and axe-shaped handles, and carenated cups or bowls with horizontal parallel grooves below the rim.

In sector E, the area at the edge of sector C was investigated, where work had been suspended in 2008. A stratified cumuliform deposit was also present here, formed by yellowish layers with a sand and gravel matrix alternating with greyish-brown layers with a silty matrix, containing an abundance of archaeological materials (us 3099-3100, 3101, 3102). This was probably a localized dump which could only be partially investigated due to its proximity to the excavation edge.

The structural evidence in the horizons examined was difficult to interpret.
During the 2013 campaign, the excavation of a series of cobblestones spreads used for land reclamation), which ran lengthwise across almost the entire sector was completed (us 3073, us 3074, us 3083. They were partially excavated in 2011 and 2012.
The typology of the finds was uniform and characterized by a prevalence of truncated horn-shaped handles datable to the Middle Bronze IIA.
