Abstract Superficial (1-2 cm) sediment samples from Lake Taupo were analysed for total carbon, nitrogen, andphosphorus. Theseelements essentially represented organic material, though with some modifications for phosphorus. Average concentrations, in mg g-
1 were: C = 25 ± 9.6, N = 2.2 ± 0.8, P = 0.7 ± 0.3 (n = 75). Organic sediment focusing with depth was found to have a minor effect on the distribution of C, N, and P, and their variations across most of the lake are not great. Most effect on distribution is caused by river inflows, but whereas the southern influents create zones of low C, N, and P (diminished organics), those further north are associated with locations of elevated C, N, and P (enhanced organics).
