Short summary
High-resolution phosphorus and flow data were used to gauge the effects of diffuse (soil P) and point source (septic tank system) mitigation measures in two flashy headwater river catchments. Over 4 years the data indicated an overall increase in P concentration in defined high flow ranges and low flow P concentration showed little change. The work indicates fractured responses to catchment management advice and mitigation which were also affected by variations in seasonal hydrometeorology.
