Environmental Impact Statement: Inarajan River Dam Project

At the request of the Guam Waterworks Authority (GWA), formally [sic] known as (PUAG), the Barret Consulting Group (1994) completed surface water development study for the southern Guam. The purpose of this study was to determine the feasibility of developing surface water resources in Southern Guam. According to this study, a number of potential dam sites were evaluated. One of the projects suggested is the construction of a dam and a storage reservoir site on Inarajan River, immediately downstream from its confluence with Laolao River. This Environmental Impact Statement report was prepared by Mr. Danko TaboroŇ°i and Dr. Khosrowpanah as a class project for the Environmental Impact Assessment EV 513. The format that has been used is in accordance with the Council on Environmental Quality (CEQ) regulation that set forth the National Environmental Policy Act (NEPA) procedures.

The proposed action is the construction of a dam on Inarajan River, immediately downstream from its confluence with Laolao River. For the purpose of this study, only a No Action alternative was evaluated in addition to the proposed action.

Environmental impacts from this project are anticipated in the following areas: habitat modification and loss (including impacts on terrestrial and aquatic flora and fauna); primary construction impacts; effects on cultural, recreational and scenic resources; economic impacts; impacts on existing infrastructure; impacts on loss of agricultural land; and impacts on water quality. The most dramatic impacts are expected to be on aquatic organisms and surface water quality.
