The present study was conducted from 2012 to 2014 in Lake Gudera which is located in Amhara Regional state West Gojjam Administrative zone, Sekela Woreda. Insitu measurement for pH, oxygen, temperature, total dissolved solids, conductivity and salinity measured at 4 oclock in the morning using YSI 556 multi-meter probe. Secchi transparency measured using secchi disc, depth using depth meter and the amount of nitrate, phosphate, ammonia, total hardness and alkalinity measured using Wag tech Palin test photometer 5000 immediately after sampling. Questionnaire developed and interviewed from key informants and inhabitants of the area was collected. The chemical composition indicated that phosphate, ammonia, nitrate, and turbidity was 0.18 mg L-1, 0.18 mg L-1, 1.054 mg L-1 and 59 NTU, respectively which was high exceeding the standard level set by different countries for aquatic life in freshwater bodies. The mean pH (8.38) in the littoral site which was found very approximate to the permissible pH (6.5 to 8.5) prescribed by the USEPA 2005 
Standard. The mean depth from the two study sites was 1.65 m which was 1meter by far less than the previous reports. This might have been a result of agricultural activities experienced adjacent to the Lake. Copepoda (59%) was dominant taxon which was followed by Cladocera (41%). The high level of most of the studied parameters in this study showed the water quality in this situation is deteriorating and this might have detrimental effects on the health of fish and other aquatic biodiversity in the lake.Pages: 21-26 | 798 Views 43 DownloadsDownload Full Article:
