Bruce:
You need to determine the water volume and the head in the distance of interest, 5 to 10 gallon/sec ( 19 to 28 liter/sec ) is not enough information . You need two requirements, volume and head OR volume and water velocity Flow * head = power. Low flow for an Aquair unit. For you, measure the head from intake to turbine site, then be accurate with the flow, calculate the power : use : water volume * head * 6 = watts available at generator output. This may tell you if you can use a pipe for the length of the stream to get a practical power for you. Example : 5 gallon/sec ( 19 liter/sec) and 20 feet (6 meter) head may give you around 684 watts. Small BANKI or Propeller turbine may do the job -- lastly a low Head Turgo, Michael Lawley may have what you need http://www.ecoinn.co.nz .
