River in National Land Code 1965 and Water Act 1920

I just back from Jelebu, Negeri Sembilan on yesterday and as usual the local people will post me a lot questions while I did the survey. There is a river (Sg. pertam) beside the lot and according to the owner of the land. Last month there was some cleaning activities at the side of the river and somebody want to plant oil palm along this river bank. In fact, the oil palm planting activities has been carried out by the local people for quite some time in this river bank with fencing and now they try to extend the area. Thus, the land owner want to me to verify his boundary before this "illegal" activity occur inside his land. One of the question he asked me was "what is the reserve width from river" and this question has been anwsered by one of the blogger by the name of AK7377. According to Water Act 1920 under section 14 , the reserve is 50 feet from any river bank but in National Land Code 1965, the provision under section 13 stated that the reserve is 50m from river bank.

Above information are all the sections under National Land Code 1965 related to river.
