Note - bare banks- no riparian buffer- so fine silt-soil washes into river choking much aquatic life. The Halswell suffers from soil wash off severely degrading the in-stream values of this critical waterway within the Te Waihora catchment.
Embarrassing to drive past when taking international visitors down to the river to go fishing. The lower Waimak- a braided river on our doorstep- a drain for treated industrial waste.
A small coastal stream near Taumutu, on the South Canterbury Coastline. In 2004 I was shocked to see the destruction along the entire side of the creek of a flax riparian margin over a distance of 1 kilometre. At the time I was informed that it was routine flood control - a laughable explanation for a stable coastal spring creek. Since local authorities were made aware a retrospective resource consent was given along with the implementation of an ecological restoration program- of which I was given no details. This one goes in the to follow up basket.
Photograph shows severe erosion and silt input. More care needs to be taken of the riparian margins of the Okana and Okuti Rivers- especially in there lower reaches, to contribute to an improvement in the water quality of lake Forysth- Wairewa. This photo taken in September 2008 shows how little has been done to look after a once much renown lowland waterway. With advocacy by myself and others some improvements have been made to fence out cattle but more needs to be done.
With so many lowland streams either lost water or been degraded I have found fishing irrigation raceways a rewarding experience- a bit of a contradiction- but better than nothing.
Didymo is likely to become prolific throughout the entire Hurunui River system if a dam is placed on the South Branch of the Hurunui- Didymo blooms go hand in hand with dammed and modified rivers ! (Photo shows didymo blooms in North Branch of Hurunui- stabilised naturally by lake Sumner. Didymo is now so prolific in the North branch of the Hurunui to make this section of river difficult to fish with nymphs or to spin fish).
Waiwhio- "waters of blue duck"- Irwell river- Western side of Lake Ellesmere. No longer any blue ducks and no longer a functional waterway ( a spring creek that once flowed all year- now reduced to a "baseline trickle"). Sadly all these signs are but an epitaph for the stream.
