  • 19 December 2025

    Janet Laban

    water temoerature raised above 11 degrees to carry out testing. Foam on water surface due to high water flows over the weir

  • 5 December 2025

    Janet Laban

    sampling temperature 7.5 degrees C raised to 13.1 DegreesC before carrying out Hanna Checker testing

  • 21 November 2025

    Janet Charlesworth

    Water temperature low so samples allowed to warm up at home before testing

  • 10 October 2025

    Janet Laban

    Samples were also tested at home at 11.50am with the following results: Water temperature 17.5 conductivity 878 Ammonia 0.19 Phosphate: 2.45 This shows similar results to the testing in the field

  • 3 October 2025

    Janet Laban

    Phosphate checker level 2.5 flashing indicating that phosphate levels are above the limit of this Hanna Checker
