Found that book it's called places to paddle by Gerard Effaney
Pretty good book tells you distance between stops , shallow points etc . . Remembering it was written before the big floods a few years back so I reckon the river would have changed a fair bit .
Be careful just around the corner from fern vale . There used to be a fair sized bullshark cruising around the deep parts there ,Shat ourselves when we 1st saw it .but chances are it's gone out into moreton bay with the floods as well
