Conserving wetland water by suppressing evaporation

Authors: Rutherford, R.J. And G.L. Byers
Description: There is a particular concern today regarding adequate fresh water supplies for human consumption.Watershed wetlands are a potential source of water supplies if properly man aged. Before feasible management practices can be developed or used, however, knowledge of the role of wetlands in the hydrologic cycle is necessary. This study was undertaken to investigate the management technique of evaporation suppression on wetlands to in crease water yields and augment water supplies during the dry months of the year and to evaluate the role of wetlands in water storage. The latter objective has implications for flood control. The site selected for this study was Jewell Pond, a 4.45-ha (10.9-acre) wet land located in the town of Stratham, New Hampshire. Although Jewell Pond is 4.45 ha in size, only 1.11 ha (2.7 acres) are open water surface. The remaining 3.34 ha (8.2 acres) consist of muck and peat deposits, supporting a dense growth of buttonbush (Cephalanthus occidentalis) and leather-leaf (Chamaedaphne calculata). A visual analysis of Jewell Pond is provided by the low altitude, oblique aerial photograph in Figure 1.
