It should be possible to obtain advice from the lock keepers on how to time and achieve a slack water (around the time of local HW) entry into the Selby Canal from the Ouse following passage downriver from Naburn, but this may fall outside the scope of the usual minimal and simplistic -'one standard procedure and timing will do for all occasions'- advice it seems that CaRT management have instructed their staff to pass on to those unfamiliar with boating in the tides of both the Ouse and the Trent.
In the event of your being unable to get the advice and information you want from CaRT, it is available from other sources but must, and can only, be given immediately prior to passage in order to take into account all the variables that affect it, such as predicted tide heights, weather conditions and the quantity of "fresh" (rainwater) in the river at the time.
