Re: Mountain Plover at Saltworks Pond 20

Is there any online source that shows the salt works ponds with their
respective numbers? I have a couple of aerial photos from old salt works
construction documents (retrieved online) that number some ponds but not
others. I know where ponds 10, 10A, 11, and 12 are but not 13 let alone 20.
I assume 13 is south of 12 and adjacent to the Otay River channel? A
graphic at <https://tinyurl.com/y9c3e8u3> labels pond 15 but no others. I
would guess since much of the refuge is currently closed to public access,
USFWS doesn't see a need to disseminate this info. Thanks.
