Unfortunately these dates could be wrong by several centuries from the felling date of the timbers depending on exactly which part of the timber was sampled. Moreover, because the timbers were found in the base of the Fishlake channel they must have originally been in place further upstream. The date of the timbers does not, therefore, give a date for the building of the Fishlake because they could easily have been washed out of position and travelled downstream long after their original felling and erection. However, it does show that people in the Test Valley at this time were building some structure in or alongside the Test, perhaps a bridge or causeway, a little upstream of this point. This could be a bridge on the site of Old Timsbury Bridge. It is possible that the exact line of the channel of the Test and Faibourne in this area may have been slightly different at the time but the boundary of the estate of Romsey Abbey described in the 10th century charter suggests that both the watercourses and the boundary of Romsey Infra were similar to their present courses.
