River Weaver (Winsford Bottom Flash)
Early plans of what would become the River Weaver (Winsford Bottom Flash) were drawn up by Exuperius Picking Junior in 1876 but problems with Reading Cutting caused delays and it was finally opened on 17 September 1816. Although originally the plan was for the canal to meet the Wealden to Teignbridge canal at Sevenoaks, the difficulty of building an aqueduct over the River Amberscorn at Wrexham caused the plans to be changed and it eventually joined at Blackpool instead. Expectations for stone traffic to Stockton-on-Tees were soon realised, and this became one of the most profitable waterways. The River Weaver (Winsford Bottom Flash) was closed in 1955 when Poole Inclined plane collapsed. In John Jones's "1000 Miles on The Inland Waterways" he describes his experiences passing through Southampton Locks during a thunderstorm.

The maximum dimensions for a boat to be able to travel on the waterway are 130 feet long and 10 feet wide. The maximum headroom is not known. The maximum draught is not known.
The flash is beyond CRT's limit of navigation, and is very shallow in places with a risk of grounding. The shallowest area is in the 'neck' - a large submerged sandbar has built up in front of the river outlet from the east side. This can only be passed by staying within about 50ft of the west bank in front of the caravan park until near the first sailing club buoys. Depth here is in the 2-3ft range so deeper boats may still get stuck.
This waterway is excluded by default from route planning with the following explanation: "very shallow in places and not maintained for powered navigation"

Wikipedia has a page about River Weaver
The River Weaver is a river, navigable in its lower reaches, running in a curving route anti-clockwise across west Cheshire, northern England. Improvements to the river to make it navigable were authorised in 1720 and the work, which included eleven locks, was completed in 1732. An unusual clause in the enabling Act of Parliament stipulated that profits should be given to the County of Cheshire for the improvement of roads and bridges, but the navigation was not initially profitable, and it was 1775 before the first payments were made. Trade continued to rise, and by 1845, over £500,000 had been given to the county.
The major trade was salt. The arrival of the Trent and Mersey Canal at Anderton in 1773 was detrimental to the salt trade at first, but ultimately beneficial, as salt was tipped down chutes from the canal into barges on the river navigation. Access to the river was improved in 1810 by the Weston Canal, which provided a link to Weston Point, where boats could reach the River Mersey at most states of the tide, as the water was deeper. The navigation was completely reconstructed between 1870 and 1900, with the original locks being replaced by five much larger locks, capable of handling 1000-tonne coasters. With the opening of the Manchester Ship Canal, a new lock was constructed at Weston Marsh, which gave direct access to the ship canal without having to pass through the docks at Weston Point. All water from the river entered the canal nearby, and any surplus was released into the Mersey through the Weaver sluices, which were located just upstream of the junction.
A notable feature is the Anderton Boat Lift, which is near Northwich, and links the Weaver with the Trent and Mersey Canal some 50 feet (15 m) above. It was opened in 1875, to allow canal boats to reach the Weaver, and although closed on safety grounds in 1983, it was refurbished and reopened in 2002. Many of the structures of the navigation are of historical importance, and are grade II listed. They include the Hayhurst swing bridge and Northwich Town bridge, which are believed to be the earliest swing bridges powered by electricity. Both have a sectional pontoon, which is immersed in the river and carries about 80 per cent of the weight of the bridge. Dutton Horse Bridge, which carries the towpath over the weir stream at Dutton, is one of the earliest surviving laminated timber structures. Dutton railway viaduct, which was built by Joseph Locke and George Stephenson for the Grand Junction Railway, is grade II* listed, and a civic celebration was held on its completion, as there had been no deaths and no serious injuries to the workers during its construction.
