The 2011 campaign, 11th July-5th August, concentrated on sectors D and E.

Sector D, close to the marsh at the centre of the basin and to the point where core samples were taken for paleo-environmental analyses, was opened in 2007 in order to check the sequence of horizons seen in the core samples. It is a small trench (5 × 5m), in which digging is rendered extremely difficult by considerable water infiltration.

The excavation investigated the roof of the deposit, identifying a series of layers characterised by a slight east-west slope, probably a bank area where a number of manmade gravel dumps were noted. The size of the area limited the understanding of structural aspects, but the removal of US 4012 revealed a large number of timber elements: vertical posts (many with the tops bent and broken) and a jumble of overlying horizontal timbers.

The investigated levels belong to a late middle Bronze Age horizon (BM III). This is of interest within the context under examination and within the entire Benacense region where this horizon is scantly documented by stratigraphic excavations. The dating was provided by a bronze axe with bent over wings and some pottery (including a saddleback handle with semicircular expansion, a saddleback handle with truncated horn-shaped appendages).
Sector E was opened in 2007, between sectors A/Perini and C, in order to link the sequences. The 2011 campaign was limited to the western part of the sector, closest to sector A (quadrants D-M/19-26, covering a total of 64 m2).

Levels interpreted as land reclamation were excavated, characterised by cobbles in a matrix of material brought to the site, and numerous finds including pottery vessels broken in situ.
Below these levels, the deposit took on an anaerobic character. In fact, the heads of vertical posts began to emerge. An alignment of posts was uncovered in quadrants D21-23, whose association may be confirmed by dendrochronological analyses.

The preliminary dating for the contexts with significant quantities of finds is as follows: US 3073 was an assemblage characterised by a prevalence of truncated horn-shaped handles, attributable to the BM IIA. This horizon had already been identified at Lavagnone (sector B), but in sector E it was more substantial and the stratigraphy more reliable. The layer below marked a transition phase BM IIA/BM I: the truncated horn-shaped handles were associated with earlier typologies: axe-shaped and T-shaped handles. Also present: a fragment of a capeduncola cup with fan-shaped handle (parallels known south of the Po: Chiaravalle della Colomba –PC, La Braglia –RE, or with axe-shaped handles of the Monate-Mercurago type, datable to the BM I) and a wall fragment from a biconical vase with a very large button-handle, an element previously thought to be exclusive to the early Bronze Age.
