 In contrast the middle of the river have practically no gradient and are not suitable to the development of head for industrial or hydropower projects.The three uppermost dams, forming North Lake, Kayuta Lake and the smaller Forestport Reservoir are the only structures forming significant impoundments.The other dams are run-of-the-river, with no appreciable storage capacity, so power generation is entirely dependent on the natural flow of the river combined with releases from upstream reservoirs, which is relatively consistent except for drought years.
