Report discussing "the drainage of irrigated lands which have been seriously injured or rendered wholly unproductive by the seepage of irrigation water or by the rise of alkali, or by both combined.... This report not only describes the condition of the land, the details of its draining, and the results which were obtained in particular cases, but gives carefully drawn deductions from the experiments, together with directions for draining lands which have become too wet or too alkaline under the ordinary methods of irrigation for profitable cultivation. Methods of draining are not so well established for irrigated land as for land in humid areas, which fact suggests the propriety of describing methods that have been tested in specific cases." -- p. 2

This report describes an investigation of the effects of stream channelization on fish and macro-invertebrates in low gradient reaches of Blacksmith Fork River and the Logan River in the floodplain of Cache Valley in northern Utah. Channelization adversely affected both fish and macro-invertebrate populations and biomass, with the severity of impact directly related to the amount and duration of disturbance of the physical habitat.
