The major water resource problem in the Aloha-Rigolette area is agricultural flooding. The agricultural area represents 18 percent of the basin and is nearly surrounded by wooded hill lands that constitute the remainder of the basin. Runoff from the entire basin is funneled through the flat plain of the agricultural area into a control structure located at the southern end of the basin. Other water-related resources such as fish and wildlife, recreation, and water quality were investigated. Although no problem was identified, there appear to be opportunities to enhance these resources. Throughout the planning process, opportunities for water conservation were assessed.
