Two dams, located c. 25 m apart, were excavated in a tributary of Nahal Yaval (cf. HA-ESI 120). The eastern dam (L10; Fig. 2) consisted of two fieldstone-built walls. The first (W3; 1.0 × 1.0 × 0.5 m), which was oriented along a north-south axis, was built perpendicular to the southern bank of the stream while the second (W2; 1.0 × 2.5 × 0.8 m), aligned in a northeast-southwest direction, was built parallel to the stream’s bank. The western dam (L11; Fig. 3) was located on the northern bank of the stream and it too consisted of two walls. The first (W5; 1.2 × 6.0 × 0.6 m) was oriented in a north–south direction and was built of small and large fieldstones; its continuation (W4), whose remains were found to the south of it, was destroyed by the flow of water in the stream. The second wall (W1; 1.5 × 3.0 × 0.3 m) was perpendicular to Wall 5 and was built of small stones.

The two dams were part of a system that was meant to divert the flow of the stream to a cultivated plot.
