California Condor Eban McMillan 28 april 1964 of having to replace four of the heavy padlocks that lock the heavy marble manhole covers, that are scattered along the aqueduct, just this last weekend. He showed me these four padlocks that had been hit with rifle bullets in places where they would break open. Mr. Miller said he has a bin full of damaged locks he has replaced during the last several years. He said that the L.A. Water and Power Department do not encourage arrest of those found damaging these locks. They claim it is cheaper to replace the locks. Miller gets no help from the authorities in trying to discourage this promiscuous shooting in an area that, is closed to the discharge of firearms. He maintains this unrestricted shooting goes on each weekend and that during School Vacation the tempo increases. Mr. Miller wants me to contact the aqueduct patrolman southwest of him where I would be shown how these shooters finally destroy, with rifle shooting, the six inch thick Concrete encasements that have been built by the Water and Power Department to protect expensive pizzometers that meter the altitude of the water in the aqueduct. Not only have these Concrete fortifications been broken down by rifle power, but many of the expensive pizzometers also shot to bits. Mr. Miller also stated that L.A. Water and Power Department are now planning on fencing highway aqueduct north of Highway 466,
