Oulton Broad is part of the tidal rivers Waveney. As such, the water levels go up and down. In general, until you get out of the Broad into Oulton Dyke, there is never any need to worry about which way the tide is flowing, but the different water levels can cause issues with access to the club (the tidal defence boards may be in place) or the crane (not enough water to launch keel boats).
The tide tables for Gorleston are here: Tide information (broads-authority.gov.uk). Don't forget to add 4 hours to these times for Oulton Broad.
From time-to-time, the Broads Authority dredge the Broad in order to maintain suitable navigational rights across the area. The current Ordnance Survey local map of the area, including dredged depths, is here: Depth - Oulton Broad and Dyke (broads-authority.gov.uk).
