History
Name shown as "O(strov) Gidra," or "Hydra Island," by Captain Tebenkov (1852, map 22), Imperial Russian Navy (IRN), and is shown as "Zatschra Island" on a manuscript Russian map of Kodiak (1849). An 1888 U.S. Bureau of Fisheries (USBF) chart shows "Hydra Island," apparently identical with "Otter Island," shown on a 1900 US@C&GS chart.
