Implementation of Interim IFS for 27 East Maui Streams

This section outlines the current progress on the implementation of interim IFS for the 27 petitioned streams in east Maui. The following tables include, 1) the current status of the interim IFS for each stream; 2) simplified schematic diagram for each hydrologic unit; and 3) field investigation reports of site visits conducted to implement the interim IFS. Information is organized by hydrologic unit. To view information on a particular stream, please select the stream of interest below. (Note: CFS = cubic feet per second; MGD = million gallons per day)
