1997, with above average flow each month, was followed by a record high flow in May 1998, then a sharp decline. Through diagnosing these changing flows and their expression in the Beaufort Sea via synthesis of observations and model output, this study provides insight into the nature of the Arctic's freshwater system. The low discharge in WY 1995 manifests negative anomalies in P-E and precipitation, recycled summer precipitation, and dry sur-face conditions immediately prior to the water year. The complex hydrograph for WY 1996 reflects a combina-tion of spring soil moisture recharge, buffering by rising lake levels, positive P-E anomalies in summer, and a massive release of water held in storage by Bennett Dam.
