Large Scale Lake Planning
Lake Neshonoc is a valuable water resource that is presently being degraded by deposition of sediment or sedimentation. Approximately 11 percent of the lake volume was filled between 1954 and 1985. If nothing is done in the next 30 years there will be severe impacts to the lake. The exposed portion of the delta will extend to about the midpoint of the lake near the campgrounds. This report is a study of the sedimentation problem involving four major steps: 1) data compilation, 2) data analysis, 3) outline of alternatives, and 4) recommendations.
To evaluate sediment control alternatives; Review and analyze existing data, visit site to take photographs, collect sediment samples, gather information on the lake and watershed.Develop estimated sediment budget for the lake and identify necessary sediment trap site.Outline alternatives with cost estimates for sediment control including lake dredging, sediment traps, and modification of agricultural practices.Develop recommendations for sediment control.
