The Given Coords are for a good parking spot close to the cache. From here you have a great view of the Mokelumne Aqueduct. Out here in the Delta, the aqueduct is above ground. Once it leaves the Delta, it goes back underground. East Bay Geocachers certainly have found a cache near the aqueduct before.
The Mokelumne Aqueduct (which is fun to say but hard to spell) helps supply water to the Bay Area. It was created almost a hundred years ago to satisfy increasing water demands by East Bay residents. Operated by the East Bay Municipal Utility District (EBMUD), the aqueduct moves Mokelumne River water stored in the Pardee and Comanche Reservoirs, located in the the Sierra Foothills across the Central Valley, through the Delta and up to the East Bay Hills where the water is stored in various other reservoirs before being distributes to thirsty East Bay residents.
