I have said this before but I will say it again:
Many things are possible.
Very few things are practical.
You can probably make more power by hand cranking a real generator for few minutes than you will see from a 6 foot drop and a trickle in a day.
Note I did not say it wont work.
Around here that kind of flow would be referred to as a spring or a seep, not a creek.
Anyway while it might actually work at some level because there is some power available in any moving water but there are other options that are probably much better in that situation. You either need a good fall or good flow to do hydro well. Sounds like you have neither. You could calculate the power available if you gave solid numbers on fall and flow rate but about like filling your tub is too vague to plug in to any formulas.
Good luck if you try.
