These relate to environmental conditions and differ from previously reported patterns in functional species diversity and relative abundance for aquatic animal. The condition of Nam Kene Reservior in wet season 2012 was natural stream. Flow turbulent and water velocities are high. The river bottom consists of large and small stone, meanwhile in wet season 2014 the condition was natural basin and water velocities are low. The condition of Nam Louk Reservior was upland river with 5-10 meter width and 30-50 centimeters depth. Transparent and water velocities are low. The river bottom consists of rock and gravel. While the Nam Louk Reservior in wet season 2014 was obstruct became to natural basin and low water velocities. The environment of water ways in 115 kV transmission line in wet season 2012 and 2014 were no different condition that are upland river with 2-3 meters width, shallow water with 30-50 centimeter depth. Flow turbulent and water velocities are high. In pools, the water is deeper therefore flow and turbulent is less. The river bottom consists of muddy sand and gravel.
