      Abstract
      The water quality in Lake Rotoiti has become increasingly degraded since the 1950s. Water from Lake Rotorua, with elevated phytoplankton and nutrient concentrations, has entered Lake Rotoiti via the Ohau Channel. To help improve water quality in Lake Rotoiti, a constructed wall was completed in July 2008, to divert water from the Ohau Channel towards Okere Arm in Lake Rotoiti, with the objective to transport this water into the Kaituna Rivr instead of entering the main basin of Lake Rotoiti. This report has been produced in response to a request from the Rotorua Lake Technical Advisory Group to determine water velocities in the region of the constructed wall, in order to consider the effectiveness of the diversion.
