In 2012/13 Ken navigated his houseboat Orlando in stages from Murray Bridge to Yarrawonga, juggling river heights and flows to travel over hazards and under bridges.
Here are some observations from his trip using 7th and 8th editions of River Murray Charts:
Map 9 The WDS at Wentworth is approximately 3km upstream of the Murray Darling junction or 1km upstream of the bridge.
Map 26 The clay bar at the southern end of Goat Island, opposite the caravan park, is larger than shown on the charts and extends about a third of the way into the channel.
Map 27 The Murray Downs wharf at around 1413km is a standard public waste disposal station [know locally as perfume point].
Map 38 The 263 mile tree and the 1776 km marker are both missing in The Narrows. This has been confirmed by Benita Cox who runs Kingfisher Cruises through here.
Some recommended sources of information on river heights and flows are:
