Title: Hypereutrophication of an Hawaiian Alpine Lake

Abstract: A drought during the period 1977-1978 resulted in a roughly
fourfold reduction in the volume of Lake Waiau, a small perched body of
water near the summit of a volcano in Hawaii, and an over 200-fold increase
in the late-summer chlorophyll a concentration. The normal planktonic flora
of the lake was replaced during this time by an almost complete monoculture
of the chlorophyte Nannochloris bacillaris. Nutrients required to support this
bloom appear to have been supplied by an influx of interstitial water as a
result of the development of an unusual hydrostatic head between the perched
groundwater around the lake and lake surface water. The lake had not fully
recovered from this episode 2 yr after termination of the drought.
