    In January 1991 the dam built for electric power generation at Yonki township in the upper Ramu was closed. This started the flooding of grasslands, gardens and coffee plantations in the Arona Valley. In November 1991 the reservoir, which is at 1260 meters above sea level, reached the Full Supply Level and water started to flow over the spill way. At this level the reservoir covers an area of 2200 hectares. The shoreline of the reservoir is very dendritic and has an approximate length of 50 to 6 0 km. The new reservoir is the biggest water body in the high altitude region (i.e. > 1000 m above sea level) of the Sepik-Ramu catchment area. According to the 1990 National Population Census 9179 people live in census units within approximately 6 km from the reservoir, of which 2631 live in Yonki Township. Figure 1 shows a map of the reservoir with Yonki township and some of the nearby villages.

    This report provides results and discussion of data from a fisheries survey in lower order streams of the central Highlands of Papua New Guinea undertaken from August 1991 to August 1992. The survey can be considered as an extension of a similar survey of the Sepik/Ramu catchment undertaken by Van Zwieten as part of phase one of the Sepik River Fish Stock Enhancement Project (SRFSEP) (Van Zwieten 1990).
