Abstract
A groundwater-pond (gravel-pit), dredged 6 years ago for hydrological and hydrochemical investigations, is already starting to show eutrophication. The input source is mainly confined to its surrounding groundwater, with which the pond is in effective exchange, and which contains above-normal concentrations of nitrate (ca 30mg/LN). This nitrate is substantially reduced by denitrifiers in the pond. However, the N/P nutrient ratio remains about 1000 (by weight). Measurements of primary production, heterotrophic production and biomass made during the past 4 years are discussed in relation to the outstanding nutrient situation and with respect to the pond’s trophic development.
