In maintaining health aquatic ecosystem, there is the need to have a balance biotic and abiotic factors thus this study was conducted to assess some physical, chemical and biological parameter of Lake Dangana in Lapai, Niger State for period of eight (8) month (January-August, 2020) in identified sample stations using standard protocols and procedures. The result revealed mean Temperature (23.5-26.5ºC), Dissolved oxygen concentration (3.96-4.13mg/l), Biochemical Oxygen Demand (3.00-3.12mg/l), pH value (6.88-7.11), conductivity (86.43-94.80µS/cm), nitrate (0.67-0.76mg/l) and phosphate (0.85-1.04mg/l). There was no significant difference (p>0.05) in the monitored Water temperature, Dissolved Oxygen, Biochemical oxygen Demand and pH between sampling station. However, electrical conductivity, nitrate and phosphate differs significantly (p |
