Gfci outside near a pond
All 120V 15 &amp; 20 amp outdoor outlets are required to be protected 2014 NEC 210.8.3. If they are all on the same circuit wire the GFCI outlet from the breaker on the line side. Then the wire that feeds the rest of the outlets on the load side of the GFCI and they will be protected by the 1 GFCI outlet. I would recommend "while in use" covers. This type of cover allows the outlet to be used and protects better than the water resistant outlets. I like the metal ones better but they are quite a bit more expensive.
