Usalgin

The Usalgin flows northeast from wooded hills to Nikolay Bay on the Sea of Okhotsk. Between the Magu and Kivun ranges it descends to a largely marshy coastal plain, where its course winds in pronounced bends. Near the sea it opens into an estuary affected by the tides. River water and seawater meet in the shallow bay, while the surrounding wetlands collect the drainage of this low-lying coast.
