Is Egypt arguing about water usage with any other countries?

Yes, Egypt is engaged in a long-standing dispute with Ethiopia over the construction of the Grand Ethiopian Renaissance Dam (GERD). The dam, which is being built on the Blue Nile River, is a major source of water for Egypt, and Egypt fears that the dam could reduce the amount of water available to its population and agriculture. Ethiopia maintains that the dam is necessary for its economic development and energy needs. The two countries have been engaged in negotiations over the dam for many years, but have so far been unable to reach an agreement.
