Eruvin 87: Drawing Water in the Galilee

Who's Who: Hananya ben Akavya. What's What: Avel and Tzipori (towns). The case of a water channel that crosses one's property - do you need another partition? The example brought from the water channel from Tzipori to Avel. Note, though, that the size of the water channel matters. Plus: The case of a balcony over the water - specifically, over the Kinneret (Sea of Galilee). And even a balcony over the balcony that is over the water. Plus: 3 permissions allowed to the people of Tiberias by Hananya ben Akavya (only one being the hole in the floor of the balcony).
