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 time of year (18.7 °C). More detail and general trends can be found in the charts linked here.

The water chemistry is continuing to look good at Darlow; all indicators of pollution are undetectable (ammonia, nitrite and phosphate). Temperature is still high, but much relatively low compared to the last few years (19.6 °C at 0930 on Tue 01-Aug-2023). Oxygenation (7.8 mg/L, 88 % sat.) and clarity is good. More details can be found here. Fish have been seen moving around the lake, especially near aerators, and some have been reported rising to Read more…

Latest water test results are showing that we still have good water chemistry, which gives our stock the best chance over the Summer months. Nitrate, nitrite and phosphate are all undetectable, and oxygenation is also good (105 % saturation, 9.2 mg/L). Water clarity is also good, although can become a little cloudy during warmer months. These low levels of nutrients will also help to reduce the chance of algal blooms. We did have a small, Read more…

Water temperatures are now starting to creep up (16.8 °C at 0900 on 23-May-2023), but the lake is looking fantastic with very clear water and some good new weed growth. Fish are showing all around the lake with some big tench and carp that can be seen in some swims. Also, more good news on the water chemistry, with all indicators of any pollution undetectable or very low. Oxygenation is also high (10.8 mg/L, 111 Read more…

The latest water quality tests are looking excellent. All indicators of serious pollution are undetectable (phosphate, nitrite and ammonia). A small amount of nitrate was detected which was likely to have come in from the flood water over the last few months – historically, Darlow typically has a very low level of nitrates because we have very little new water flowing in from other sources, so plants have a chance to use it. The clarity Read more…

Just a quick set of water test results prior to the start of the season. All water chemistry parameters look good; ammonia, nitrite and phosphate are all undetectable. These are all indicators of pollution or something out-of-balance, so that is great news. Nitrate and alkalinity are slightly raised but that is due to the diluted river water that has entered Darlow during the flood – about the same levels as last year. Nitrates can be Read more…

The first set of tests for 2023 are looking good. The water is cool (7.6 °C), fairly clear, and with good oxygen levels (10.6 mg/L; 88.6 %). Phosphate, nitrate and nitrites are all undetectable, and ammonia levels are very low, with a pH stable at 8.3. Lake water levels are also increasing with the depth gauge reading -0.2.
