that season again

Yes, it's that season again, when I have to say Baruch Hashem, Thank G-d, when it rains on my laundry, or my boots get filled with water.

Here in Israel it only rains in the winter, and we need every drop. We start the season with a prayer for rain on Simchat Torah, and then we add short prayers (ok a few words) to the daily prayers.

There are those who say that some of the American Indian tribes are descended from the Ten Lost Tribes of the People of Israel. There are tribes that also pray for rain. I wonder how similar the prayers actually are and if it's the tribes considered "Jewish" that have those ceremonies.
