Description	Solving the question of actual impact of non-point sources on aquatic ecosystems (mostly reservoirs in Czech Republic), we face up to several dimensions of phosphorus (P) emission, which are not satisfactorily quantified: magnitude, timing and availability. But all three are crucial in respect to development of any algal community. Moreover, before we settle somewhere with our sampling equipment to measure above mentioned dimensions, we should know about representativeness of selected profile to exclude future problem with up-scaling. To understand spatial variability in macro-scale we underwent whole-country screening during summer baseflow condition, because: i) highest P concentration during summer is expected, ii) summer is the season when highest abundance of phytoplankton (also cyanobacteria blooms) does occur and iii) P emitted during quiet period is most prone to uptake. In result and with respect to Czech agricultural context we focus mostly on non-erosional P flowing out from arable land.
