That these plansand specifications as workedout contain every safe-guard that expert engi-neers can suggest goes with-out saying. GENERATION AND DISTRIBU-TION PLANTS It must be understoodthat the main generatingstations of the canal are atthe Gatun Dam at the At-lantic end and Miraflores at the Pacificend of the lake. There is also a smallerstation at Pedro Miguel at the end of theCulebra Cut. To get the idea clearly intothe minds eye: after coming in from theAtlantic Ocean by Colon through LimonBay the canal is lifted at Gatun by a.
