(Mishnah): If a channel of water passes through a Chatzer, they may not draw water from it [on Shabbos] unless they made a Mechitzah 10 Tefachim tall where the channel enters and leaves [the Chatzer];

R. Yehudah: A case occurred in which they drew water from a channel in Eivel on Shabbos, based on Rabanan! (The wall of the Chatzer suffices, like R. Yehudah taught in the previous Mishnah.)

Chachamim: [No, they permitted] because [the channel] was less than the Shi'ur [to be a Karmelis].

(Gemara): Our Mishnah discusses [a channel] 10 deep and four wide, and it leaves the Chatzer here and here [on both sides].

If [the channel leaves the Chatzer] on one side, he puts a Lechi or Korah here [at the exit, to permit carrying in the Chatzer, lest it be breached to Karmelis. The Yerushalmi holds that the wall of the channel does not permit, for we are concerned lest debris be deposited and it will cease to be 10 deep. If it leaves] here and here, he puts a Lechi or Korah here [at one exit] and Tzuras ha'Pesach here (at the other exit, like a Mavuy Mefulash).

Question: (The channel splits the Chatzer into two.) Does it not turn out that two Reshuyos use one Reshus?!

Answer (R. Yosi bei R. Bun citing R. Shmuel bar Rav Yitzchak): The case is, there were houses [only] on one side. (PNEI MEIR, MEICHAL HA'MAYIM.)

The following is obvious. If it was 10 deep and not four wide, one may carry and draw water [from the channel, for it is Mekom Petur].

Question: If it was four wide and not 10 deep, obviously one may carry [in it. Since it is in Reshus ha'Yachid, it is not a Reshus (Karmelis) by itself.] May one draw water [from it]?

Answer #1 (R. Chinena): It is permitted.

Answer #2 (R. Mana): It is forbidden.

Question: A Beraisa argues with R. Chinena! [Chachamim] told [R. Yehudah that they permitted] because [the channel] was less than the Shi'ur. It was not 10 deep and not four wide;

Inference: If it were 10 deep and not four wide, it would be forbidden!

Answer: Even if it were four wide and not 10 deep, it would be permitted is forbidden. The case happened to be [that it was not 10 deep and not four wide. We explained this like SHA'AREI TORAS ERETZ YISRAEL.]

(Mishnah): If a balcony is above water, one may draw water on Shabbos only if he makes [a hole in the balcony and] a Mechitzah 10 Tefachim tall above or below.

Similarly, if two balconies are one above the other, and a Mechitzah was made only for the top one, both are forbidden unless they are Me'arev together.

(Gemara) Question: (If two balconies are adjacent, the Reisha permits both to use the water below.) Does it not turn out that two Reshuyos use one Reshus?!

Answer (R. Ze'ira citing Rav Yehudah citing Rav): The wall must be submerged in the water the full [height] of the bucket.

(Rav Huna): The wall must be within three Tefachim of the balcony.

(Beraisa - R. Chananyah ben Akavyah): A balcony above water, he makes an opening in the balcony, lowers [a bucket] and draws.

(R. Yakov bar Acha citing R. Yosa): The hole must be four by four Tefachim, and the walls [around the balcony] must be 10 [Tefachim] tall.

There (in Bavel) they say that even if the walls are not 10 tall, if [the balcony] is four Amos wide (we view the sides around the hole to bend down 10 Tefachim, and] it is made like a pointy strainer. (We explained this like SHA'AREI TORAS ERETZ YISRAEL.)

(Rav Idi, in front of R. Chiyah): One may draw, but one may not spill [through the hole].

R. Chiyah: When we appoint Chachamim, we will count you with them! (You said a great Chidush.)

(R. Mana): He was jesting with him. (We do not distinguish spilling from drawing.)

(R. Yosi bei R. Bun): [R. Chiyah] said that [R. Mana] said a proper teaching. One may draw, for he draws from [water within] his Mechitzah. One may not spill, for he spills [and the water goes] outside his Mechitzah.

(R. Chiya bar Ba): R. Chananyah ben Akavyah said [that one makes an opening in the balcony, lowers and draws] only for Lake Tiverya, for mountains surround it (they are like walls).
