Several old oxbows have been dredged and reconnected on both sides of the main channel; at each site, the former main channel was blocked by a gravel dam to redirect all flow through the new meander; the remaining old main stem stretches serve as new flow protected habitats (new oxbows) and their depth and width variability slightly improved by alternating sand bars.
