I've got a sentence, 'Robin waded out, lower down the stream'.
Is it accurate? Is it colloquial or it is rather formal? The problem is I haven't come across the structure like that so far, or at least I don't remember about it. Especially, I've confused with 'lower' used in the line. Could you please rewrite it in a simpler way or give me some explanations? I think the problem is about I can't recognise the meaning of 'lower' in this context.
Dear teachers, I would be grateful if you would right my writing.
Yours sincerely, Alex.
A river flows from A, through B, C and D, until it enters the sea at E.
B, C, D and E are downstream of/from A; C, D and E are downstream of/from B; etc.
A, B, C and D are upstream of E; A, B and C are upstream of/from D; etc.
If you are at C, and Robin wades into the river at D, he is downstream of you, or lower down the river.
