A consistent freak act of nature allowed the Egyptians to harness the capabilities of the Nile River. While the majority of Egypt was and still is covered with the aforementioned sand, the river basin next to the Nile boasts wildlife and fertile soils. This is all due to the predictable rise and fall of the Nile's water levels each year, known as inundation (rise) and relinquishment (fall). During the inundation period, which takes place sometime around July, water would rise and fill canals made by Egyptian laborers. Sometime around the end of October, the river would begin to recede, leaving rich silt deposits.
