Dense #AquaticPlants kept Spree River levels steady despite a near 50% flow drop https://phys.org/news/2026-02-dense-aquatic-spree-river-steady.html paper: https://www.sciencedirect.com/science/article/pii/S0022169425022231

"aquatic #plants can compensate for declining water levels in a drier #climate. In recent summers, their growth in the lower part of the Spree has led to an increase in water levels. They retain water not only in the riverbed, but also in the adjacent floodplain aquifers, thereby stabilizing the water balance and protecting important floodplain moorland areas."
