Hudson River Estuarine Research Reserve System as the Hudson River National Estuarine Research Reserve. The Hudson River is navigable by large steamers up to Troy, and by ocean-faring vessels to the Port of Albany. The original Erie Canal, opened in 1825 to connect the Hudson with Lake Erie, emptied into the Hudson at the Albany Basin, just south of the Federal Dam in Troy (at mile 134).

Total meandering ratio of the whole river is 65:109 (in the valley 15:33), thus the name ("Krivaja"; Serbian for "winding river"). The village of Turija stands on the Krivaja's mouth into the canal, at an altitude of 76 m. The Krivaja drains an area of 956 km, belongs to the Black Sea drainage basin and it is not navigable.
