The locks on the River Thames are used to manage water levels, control the flow of water, and assist boats navigating along the river. They allow boats to move between different sections of the river that have different water levels, preventing flooding in some areas and ensuring a consistent depth for navigation.
Generally, the boat approaching the lock at the same water level as is in the lock, has priority. All things being equal commercial takes priority over pleasure craft.
Yes the are boats there you can ride on.
The locks of the Erie Canal service barges and recreational boaters by raising and lowering them so they can get through the canal. The 34 locks separate the Hudson River at Waterford with the Niagara River near Buffalo.
Dams - yes, locks - no
A series of Locks and Dams raise and lower water levels along a river to allow boats to pass through uneven water terrain.

The locks, weirs and barrages basically enable the passage of boats through the enormous length of the Murray River. Bear in mind that, as the Murray River flows down from the Australian Alps towards the sea, its elevation changes dramatically. From Blanchetown to Mildura, each lock and weir changes the water level by 3.1 metres, enabling navigation between the mouth of the river and Wentworth. Prior to the construction of the locks, the river was not continously navigable. The locks and weirs also enable a fairly constant pool level, which helps pumping of the water for irrigation and water supply, while weir 9 specifically raises the water level high enough to allow gravity diversion to Lake Victoria. Unfortunately, the locks, weirs and barrages also change the natural flow of the river, and have therefore changed the ecosystem and environment of the river.
