This week’s water testing has shown that ammonia levels are continuing to increase (0.35 mg/L at pH 7.8). Oxygen levels are similar to last week (6.5 mg/L, 60.4 % sat. at 12.5 °C). Water clarity is appearing to improve as the suspended material falls to the lake bed.
Increasing level of ammonia is likely to be a result of the continued breakdown of plant material (including algae).
Despite being in flood, water tests are looking fairly typical for the time of year, although if the water continues to flood in we will start to see nitrates and phosphates rise higher and this Read more…
After the flooding, Darlow has now frozen around much of the perimeter, but we’ve kept monitoring the water chemistry due to the chance of increase levels of ammonia, nitrates, nitrites and phosphates coming in in Read more…
All looking good on the water chemistry front! No signs of any indicators of pollution and the oxygenation is good, even after the weed cut in early September. Water temperature is still high for the Read more…
