MM,
My creek has alot of volume, but not much fall. The banks average 25'across and 6' high, but normal water depth is around 2'. Just guessing, i would need a wide paddle(3-4'?) situated in a natural deep channel. Due to the seasonal flood, the powerhead would have to be anchored firmly to the floor of the creek so that it would remain on the bottom until the flood waters receded. This is a pic of flood stage from ontop of the county bridge. Normaly the water is 6-8' lower....
The power need will be a 1600 sq ft log home, and a medium sized barn. I want to be off grid as much as possible: wood heat w/hot water coil in the firebox, solar hot water panel for summertime, more than likely no a/c.
