    @gsp follower, thank you for your comment...here is reference to this from the email...

    Lake Tutira experiences periodic blooms which can be unpredictable, so we have placed permanent warnings at this lake.


    Our whole point is why cannot permanent warnings be placed at river access points...didymo warning signs are everywhere...I wonder who produces those signs or would it be fish and game...I have received no email from Fish and Game...yet...
    ...amitie, respect mutuel et amour...

    ...le beau et le bon, cela rime avec Breton!...

    lake tutira that brings back memories i got a bit brahms and list at the tutira pub and ran into a bank on the way back to the farm

    methinks another permenent set of bad news signage might be the straw that broke the camels back for our clean green tourist mecca.
    after all remember we are almost just tenents in our own country and here on sufferance to serve the tourists and supply not to expensive labour for the the big interests
    imagine the impact of posts at the local water hole with several warning signs ala the situation we used to shake our heads at in the states.
    they have a solution here tho you simply suck off all the water for irrigation and washing down cow yards
    after all algae can survive on dry land for long and who cares about fish and fowl theres no money in them.
    well none you can farm out of them??yeeet.
    but mallard farming is on the up in auckland/waikato eastern by preserves with strictly charitable intent ofcourse, permitted by doc behind f&g,s back, and someones constantly trying to moot trout farms
    whats a dog or two to algae bloom in the scheme of things 1080,s showed us that a dog or 10, horses, cattle deer? everythings explainable and as long as butts are covered she,l be right.
    the end always justifying the means ofcourse.
    sorry for the rant eebees but the interconnection of all this shit when it impacts on not just us pisses me off

    @gsp follower, I appreciate your rant and I thank you...you raise some very salient points, actually, which I had not thought of...clean green...yes, and was it not DOC who poisoned a river to kill the trout...dumb...the so called protected native flounder et al...did they not die as well, along with the snails and every other goddam critter in the water...I have lost a dog (albeit by other means) and I know only too well the absolutely devastating heartbreak of that and if just one dog can be saved by a sign then we will have achieved something...but as they say, its only a dog...we will press on, however...

    if algae killed one doc/dhb/regional councills sychophants ''fat phychopathics wives''[thanks pink floyd] lap polisher.
    there,d be signs from arsehole to breakfest.
    im surprised theres less hard info on what accelerates or causes the blooms here given its every summer for the last 3 or 4 years.
    Satellite image of Lake Erie showing a mild harmful algal blom in the southwestern portion of the lake.

    Harmful algal blooms (HABs) occur when colonies of algae—simple plants that live in the sea and freshwater—grow out of control while producing toxic or harmful effects on people, fish, shellfish, marine mammals, and birds.

    While we know of many factors that may contribute to HABs, how these factors come together to create a 'bloom' of algae is not well understood.

    Studies indicate that many algal species flourish when wind and water currents are favorable.

    In other cases, HABs may be linked to 'overfeeding.' This occurs when nutrients (mainly phosphorus, nitrogen, and carbon) from sources such as lawns and farmlands flow downriver to the sea and build up at a rate that 'overfeeds' the algae that exist normally in the environment.

    Some HABs have also been reported in the aftermath of natural phenomena like sluggish water circulation, unusually high water temperatures, and extreme weather events such as hurricanes, floods, and drought.

    People often get sick by eating shellfish containing toxins produced by these algae. Airborne HAB toxins may also cause breathing problems and, in some cases, trigger asthma attacks in susceptible individuals.

    HABs can also be costly in economic terms as well. At present, HABs cause about $82 million in economic losses to the seafood, restaurant, and tourism industries each year. HABs reduce tourism, close beaches and shellfish beds, and decrease the catch from both recreational and commercial fisheries.

    NOAA scientists continue to monitor and study HABs to determine how to detect and forecast the location of the blooms. The goal is to give coastal communities advance warning, so they can adequately plan and deal with the adverse environmental and health effects associated with a harmful bloom.

    Algal blooms in lakes

    Algal blooms. The algae that commonly grow in lakes are a free-floating form (phytoplankton). Some species are cyanobacteria that have the potential to grow rapidly to form a high density of cells (bloom) and produce cyanotoxins. In Canterbury, Lake Forsyth/Te Roto O Wairewa forms a bloom of the cyanobacteria Nodularia in most summers. This alga produces the toxin Nodularin, which has been known to kill stock and dogs that are in contact with lake water during a bloom.
    [AS DOES LAKE ELLY] my add in
    Algal blooms in lakes or still waters are commonly blue-green in colouration, but can also be red or yellow. They typically form thick scums on the surface, and may also develop foams at the water's edge.

    What causes cyanobacteria algal blooms?

    Warning sign. The presence of extensive mats of cyanobacteria is linked with environmental conditions conducive to their growth. Favourable conditions include the right combination of warm temperatures, sunlight, low or stable river flows, and nutrients. The occurrence of mats or algal blooms is a natural phenomenon, but human activities, such as taking water from rivers or adding nutrients to waterways, can make things worse.

    Are cyanobacteria always toxic?

    No. There are several species of cyanobacteria, that may or may not be toxic, depending upon prevailing environmental conditions. However, if potentially toxic cyanobacteria are present in large numbers, you should presume that the water may be unsafe for contact recreation or consumption.
    GEE YA FUCKIN THINK????

    Some algae have toxins in their cells, and can be harmful if they are consumed. Such algae present a risk to dogs which may eat algal mats, or ingest algae when they drink water from a watercourse. Other cyanobacteria may release toxins into the water surrounding them, which can affect those that contact or drink the water.
    bit of a telling ommission from enviroment canterburys info .
    not one mention of agri or city runoff
    no surprises there from the present government appointed board

    District health Boards / medical officer of health is my bet. Write or email to the Director General of Health in the Wellington head shed under the OIA and Ombudsman's Acts and request clarification of responsibility to public (not animal) health with regard to algal blooms and in particular Blue / Green Algal blooms
