Nepal has carried out studies on the feasibility of having navigational use of the Gandaki river. Studies indicate that (a) it is feasible only in the lower reaches, (b) link it with India’s number 1 highway from Allahabad to Haldia, and (c) cognizance has to be taken of the adverse situation which could arise due to increased irrigation use in dry seasons which could restrict the river level for maintaining possible navigation.[citation needed]
