Abstract

Kware lake is a popular natural lake in Sokoto, its known to be used for domestic purposes, irrigation practices and fisheries. Anthropogenic activities are routine at the catchment area. Water and phytoplankton samples were collected for five months. Standard procedures were adapted for determination of physicochemical parameters viz; temperature, depth, turbidity, nitrogen, phosphorus, dissolved oxygen (DO), biological oxygen demand (BOD) etc. These parameters were observed to have varied within the period of study. Five species of phytoplankton were identified, Volvox globatorrecorded the highest percentage distribution during the study. The irregular fluctuations and variations observed between the parameters studied does not  exceed the limit approved by WHO and EPA.Keywords: Kware Lake, Limnological, Phytoplankton, Variables, Water
