History
The wide, low-lying tidal estuary of the River Mersey has always been subject to flooding on high tidal events. On 20 January 1862, a flood tide covered large areas of adjacent land, which was known as Frodsham Marsh, and the highest extent at Frodsham was recorded by a small tide stone marker. This point was in the garden to the rear of the former Old Hall Hotel, some 5-7m above mean high tide, and 2,695m (2¾ miles) from the River Mersey and 1,259m (¾ mile) from the River Weaver. The tidestone has a close relationship with an earlier stone recording a flood event in 1802, which is situated approximately 12.5m to the north-east.
