A reservoir of the Nile located in southern Egypt and northern Sudan, created by the Aswan High Dam after 1971.

Lake Nasser, created by the construction of the High Dam at Aswan, is 298 miles long and 10 miles wide at its widest point, with a water capacity of 130 million acre-feet, of which 24 million acre-feet serve as dead storage for sediment and 73 million acre-feet as live storage. About one-quarter of all the Nile waters entering Lake Nasser are lost to evaporation and seepage. The largest man-made lake in the world, Lake Nasser has a major role in Egypt 's fishing industry, yielding 15,000 to 25,000 tons per annum. Original hopes that Lake Nasser would also support agriculture in its vicinity, however, have yet to be realized.

In 1978 the Ministry of Irrigation authorized construction of the Tushka canal to carry away surplus water from Lake Nasser to the New Valley Project in the western desert in case a high flood upstream caused Lake Nasser's waters to pass over the spillway, leading to damage to barrages and bridge abutments downstream. This emergency canal was used for the first time in the late 1990s, at a time of unusually high Nile flows. At the beginning of the twenty-first century, the Tushka diversion was a source of international controversy in that the Egyptian government announced plans for routine diversions of lake water into the western desert to reclaim land. This came at a time when the ten riparian states of the Nile Basin were attempting to reach an accord on future uses of the limited waters of the river.

Broadly speaking the year is divided into two seasons winter and summer (northern hemisphere).

Season A – from February to end of July
from approximately mid March through to the end of July the Nile perch are found in shallow water. This is because the Tilapia, the Nile perch’s principal prey, are spawning and then after spawning the huge population of Tilapia fry are growing up; all this takes place in water between 10 to 20 feet. This is the best time of the year for shore fishing and fly-fishing. Trolling provides good sport using shallower lures. There are still a lot of big Nile Perch around but they tend to be less concentrated than during Season B.
August and September are very hot on Lake Nasser

Season B – from mid October until end of January
The lake is at its highest level and the Nile perch are found in deeper water. We feel that the bigger Nile perch are feeding up and then coming together to get ready for spawning which takes place sometime in January / February. Year after year we capture bigger fish during this season and almost all these fish are caught trolling over underwater promontories and sunken islands. The winter months are not the best time for shore fishing. Also, fly-fishing is difficult because it is harder to get down to the fish lying in deeper water.

If you want to capture the big fish then Season B is your best bet. Season A will provide you with more action and fun but the average size of the fish captured tends to be smaller. When referring to smaller Nile perch we are talking about fish between 15 and 30lb while the bigger Nile perch can grow to 200lb + . Please take into consideration that the months of April & May – October & November are very high season and are often booked up well in advance.
