I recently visited the Kiwitea Stream in the Manawatu. I noticed some extreme river works had been done to the entire stream channel that has resulted in a mass sediment load to the reach. This can result in degraded spawning habitat, reduced interstitial dissolved oxygen and reduced habitat quality for the entire stream fauna. I lodged this with Horizons Regional Council Pollution hotline on December 30th. Today is January 18th and I'm still waiting for a response. I wouldn't call it a hotline!
