A level assembly for a wading rod used to measure current flow velocity of a wadable body of water, such as a stream or a river. The level assembly includes a level body that is attached to the hexagonal or depth rod of the wading rod at a desired position using a fastener. The level body has a level indicator to determine whether the wading rod is plumb. An alignment bar is attached to the level body and positioned parallel to a wading tagline to aid in maintaining a perpendicular orientation of the wading rod. The level assembly can be repositioned by loosening the fastener, sliding it up or down the depth rod, and re-tightening the fastener at another desired position. The level assembly is used to maintain a level and perpendicular orientation of the top setting wading rod to the tagline, enabling more accurate flow velocity measurements.

An improved bucket wheel assembly with a center frame, having a plurality of fingers extending therefrom. In each of the fingers a slot is formed. The assembly also includes a plurality of conically shaped hollow cups. The hollow cups each have a wall that forms an apex and a circular opening. The hollow cups may also have a second slot formed by two substantially parallel protuberances on the inner surface of each hollow cup. The hollow cups are attached to the center frame by matching the slots and sliding one into the other, so that a portion of the finger is between the protuberances, from the opening of each hollow cup. The hollow cup is slid into the slot until it reaches the bottom of the slot on the finger.
