of Haryana and Pujab) nahri (canal-irrigated land), nali or naili (fertile prairie tract between the Ghaggar river and the southern limits of the Saraswati channel depression in northern Hissar district of Haryana that gets flooded during the rains), and Rangoi tract (an area irrigated by the Rangoi canal made for the purpose of carrying flood waters of Ghagghar river to dry areas). Hisar has fertile alluvial soil interspersed with highly permeable very sandy tracts in bagar tract several with water table more than 100 feet below ground containing brackish water usually unfit for human consumption, where dust storms frequent during the warm summer months from April till the end of July when monsoon arrives. Previously, Hisar was solely based on the rain and irrigation was possible only in the nali region where the season Ghaggar river flows in North Hisar. After the opening of Bhakra Nangal Dam canal system in 1963 as well as the earlier Western Yamuna Canal now irrigate most of Haryana including all of the Bagar region falling in Haryana on its western border.
