Impact of drainage water inflow on the environmental conditions and fishery resources of lake borollus OceanDocs
Al Sayes, A.; Radwan, A.; Shakweer, L..
The brackish water lake Borollus occupies a central position at the north between the two branches of the Nile delta. This lake has a particular importance in the fish economy of Egypt. Therefore environmental and fisheries investigation was carried out at the lake during 2000–2002, where 15 stations covering the whole area of the lake were sampled. The present study points out that: 1. The water transparency of the lake is low where the average Secchi disc depth ranged between 21.14 cm and 43.89 cm. 2. The average water temperature attained its minimum in winter and ranged between 16.20 °C and 17.80 °C. The highest temperature was in summer where it ranged between 28.33 °C and 28.52 °C. 3. The recorded pH values indicate that the lake water was generally...

Impacts of drainage water discharge on the water chemistry of Lake Edku OceanDocs
Shakweer, L..
Lake Edku which is considered as important fishing area in Egypt receives its water from two sources. The main source is the drainage water of Kom Belag and Bersik drains where it is annually supplied with 1836.55 × 106 m3 of water. The sea water of Abu Qir Bay enters the lake sometimes through the lake sea connection as subsurface water current under the action of wind specially in winter. The present study pointed out that the water temperature of the lake (22.38oC) was slightly higher than that of the drains average (21.70oC). The average values of total dissolved solids were 1.88 and 1.44 g/L in the lake and drainage water respectively. pH values indicated that both the lake and drainage water were always on the alkaline side where the average values...
