This map illustrates satellite-detected surface waters along the Mazaruni river in Cuyuni-Mazaruni Region of Guyana as observed from Sentinel-1 radar image acquired on 23 June 2021 at 22:15 UTC. Within the analyzed area of about 480 km2, the water extent appears to have decreased of about 3 km2 since 9 June 2021.

This is a preliminary analysis that has not yet been validated in the field. Please send ground feedback to UNITAR-UNOSAT.

Important note: Flood analysis from radar images may underestimate the presence of standing waters in built-up areas and densely vegetated areas due to backscattering properties of the radar signal.
