Liz: My suggestion would be to take some measurements. Any recommendations are useless without knowing what you have. I would measure the flow of the current near your island. The flow will normally be faster on one side than the other, so I would measure both sides, unless it is readily apparent which side has the faster current. I would also suggest that you take your measurements when the river flow is below 2,000 cfs, as it currently is. (Asheville gauge reported 1860 cfs, today) The 2500cfs reading earlier in the week was a rain run-off inflated figure. Simplest way is to run a couple of strings across the stream/river 50 feet apart. Drop a small block of wood 20-30 feet upstream of the first string. Start timing as it passes under the first string, stop timing when it passes under the second. I am assuming that the main river will be too wide for the string technique, but you can set up a couple of pieces of wood or pvc pipe and sight along them. You divide the distance (50 feet) by the time and this will yield the current speed in feet per second. (example: 10 seconds for the float to pass the two marks 50 divided by 10 equals 5 fps) With a realistic current speed, we may be able to come up with something. As far as the spring, we need to know how high up it is, and what the flow is in gpm. You can install a pipe with a temporary dam of earth or sand bags to capture the flow of the spring. Once the flow is completely diverted into the pipe, you can place a 5 gallon bucket under the pipe and time how long it takes to fill. Divide the 5 gal by the number of minutes to get gpm. Once we have this height and flow of the spring, we will be better able to tell you if it has any potential for hydro. Oso ------------------------ Yahoo!
