Water is drawn from the reservoir through two screened intakes located at different elevations, which may be utilised together or separately depending on reservoir conditions. At full supply level the reservoir is approximately 25 high in area with a maximum width of 260m, approximately 1.85km long and has a storage capacity of 3.2mcm. It has a maximum depth at the dam of 36.5m and a mean depth of 12.8m. The Millet Road was improved to provide safe movement of construction equipment in and out of the site. A 1.8km access road was constructed from the Millet Road to the dam site.
Electrical power is provided by an overhead power line.
Rock for construction of the dam was quarried from borrow areas developed in the valley near the dam site. Overburden from the quarry section and the dam footprint was placed in specially constructed disposal areas. Vegetation in the reservoir was cleared and either burned on-site or transported to a suitable disposal area. This led to a junction tank on the Millet River water transmission line. The combined Millet and Roseau water flowed by gravity through an existing water line to Sarot.
