There’s a lot of commentary in the media about swimmability, which sometimes can be confusing. For example, high flows and floods during winter unfortunately means swimmable rivers 100 per cent of the time will never be a reality. We recognise the importance of being well informed, and that is why every week during summer we will be monitoring the health of over 80 swim spots to provide you with reliable information on the potential health risks in our waterways. The good news is that Horizons’ swim spots are swimmable the majority of summer. Not only are these popular sites excellent for swimming, they often include picnic and camping areas, bush walks, and toilets, making them a great place to spend with family and friends. We encourage you to get out there and enjoy them. To find out the current health of your favourite swim spot visit the safe swim spots map.

From rafting the Rangitīkei and picnicking in the Pohangina, to swimming at South Beach and fishing at Foxton, our region is full of fantastic swim spots ready for you to enjoy this summer.
Plus we’re offering you the chance to #swiminourregion and WIN! Check out the video of our first year's winners who went whitewater rafting in the Rangitikei River >>> How to enter: Simply post a pic of your favourite swim spot to our Facebook, Instagram or Twitter accounts with #swiminourregion. However make sure we see it! Feel free to send it to use by private message if you're unsure if we saw it. Also be sure to tag the Horizons Region location too, and you're in the draw to win a family adventure package for four, up to the value of $1,500 inc GST.
We often hear about levels of bacteria (E.coli) or potentially toxic algae as indicators of water quality but what are they? Why do we measure them and why do we need to be wary if they reach high levels? Common sources of E.coli are untreated human wastewater discharges, stormwater run-off and animal waste. Too much E.coli means that the water is unsafe to drink or swim in and can cause infection. Cyanobacteria (commonly known as potentially toxic algae) inhabit all natural waters and usually only become a problem when they increase to high coverage,
forming excessive 'blooms', this is usually during summer when it's warm and river levels are stable. Cyanobacterial species are known to produce toxins that can be a threat to humans and animals if consumed or contracted during recreational activities so Horizons will always look for potentially toxic algae when monitoring a swim spot.
Our swim spot and other monitoring programmes help inform our regulatory and non regulatory work initatives aimed at improving water quality. Regulatory measures include the One Plan, and working with city and district councils to ensure their wastewater treatment plants are performing as they should be. Our non regulatory initiatives include the Manawatu River Leaders’ Accord, Horowhenua Lake Accord, creating planted riparian strips to absorb nutrients and filter run-off before it enters our waterways, and fencing streams and rivers to exclude livestock. We also have the Sustainable Land Use Initiative (SLUI) which aims to reduce sediment (a source of E.coli and phosphorous) entering our rivers via run-off from the region's hill country land. A Landcare Research report which assessed the impact of SLUI on sediment levels in the region's rivers, was commissioned by Horizons in 2013. The closest scenario to how SLUI currently operates predicted the annual sediment load in rivers will reduce by 27 per cent as a result of SLUI works by 2043.
