You and the other farmers of the valley know the rivers are the life blood of the
land. The fields it flows through are fruitful and bring wealth to those owners. Each
round, farmers can harvest and sell crops from their fields, if they are able,
and then use the profits to build building structures or dam up one of the two rivers using lumber they acquire. The first to build 4 casas and 1 hacienda (or 3 houses along the river bank, along with the hacienda) is the winner!
