Repairs have been made to 30 of the 200 locations along local streams damaged during the April 29 floods.
Bay of Plenty Regional Council had completed repairs along the lower Ngongotahā, Utuhuina and Puarenga Streams, Rotorua catchments manager Helen Creagh said.
"We made it our first priority to survey the whole Rotorua Lakes area and reduce further flood risk by removing the highest risk stream blockages caused by the storm," she said.
"Since then our staff have been working through a prioritised list of sites where erosion repair or debris removal is needed to reduce ongoing risk to buildings, access or of debris dam formation."
To date, more than $100,000 has been spent by the regional council on stream clean-up and repair work including the removal of at least 10 truckloads of logs, mulched bamboo, willow, and other debris from the Ngongotahā Stream.
