Baffin Bay, also known as Lago de la Santísima Trinidad and Salt Lagoon, projects inland from Laguna Madre. Its center point is about 27°15' north and 97°31' west. The bay forms part of the eastern boundary between Kenedy and Kleberg counties. The west side of Baffin Bay connects with the mouth of Los Olmos Creek, which flows from the Laguna Salada, Cayo del Grulla, and Alazan Bay. Baffin Bay provided Confederate blockade runners with protected overland access, through the shallow Laguna Madre, to the cotton markets of Mexico. The entire south shore of Baffin Bay forms the northern boundary of the vast Kenedy Ranch (see KENEDY, MIFFLIN).
