Overview

Excerpt from Advance Report on the Sedimentation Survey of Lake Bennett, Conway, Arkansas: November 2-22, 1935 It is the Opinion of Col. Sturgeon that a large part of the silt now lying in the reservoir was deposited during heavy rains which ao curred before actual storage began. This survey, however, furnished no basis for determining the extent to which this may be the case. Aside from.this, in considering the rate of sedimentation two limitations on the survey data should be taken into account. First, the influence of erosion-control measures in the reservoir watershed, completed according to the demonstration project working plans since the reservoir was built, should become progressively more effective in reducing sediment output from the watershed. Second, a period of months is too short in any case to give a reliable indication of the silting rate to be anticipated. A period of several years, at least, will be necessary to establish an average rate of sediment output based on variation in climatic and vegetative factors and average effectiveness of erosion-control measures.
