    Lordship Recreation Ground (Downstream) by Caroline Jepson

    The water level was as high as it gets at the testing point, as there has been a lot of rain in the previous week. The depth was about 60 cms, which is about 20 cms deeper than average. Unfortunately I did not have a phosphate reading, as I made a mistake in the process (kept showing Inverted). I have since realised what I kept doing wrong! The ammonia readings continue to be the lowest ever recorded. High rainfall and water levels must help this, but I have recorded much higher ammonia levels in periods of heavy rainfall in the past.
