Relocation of Stickleback

This is an interesting post made by the U.S. Fish and Wildlife Service about a relocation of unarmored threespine stickleback in June of 2015 where they moved a population from the Santa Clara River (where drought conditions were severe) to San Francisquito Creek. This was done to protect the highly endangered fish from extinction. From my observations it seems they are now extirpated from the rescue site.
