The temperature is rising rapidly, but the water chemistry is still looking fairly good. Phosphate, nitrate and nitrite are undetectable; we have a very small amount of ammonia (0.03 mg/L, pH 8.5), but this may just be a temporary fluctuation, and it is not so high that it is a Read more…
Today’s water testing brings us some good news in that the levels of total ammonia have reduce to undetectable levels, which means that ammonia is no longer a toxic risk to the fish. Last time we saw this was during the summer of last year. Turbidity of the water has Read more…
Latest water tests have shown that ammonia levels have decreased again (0.14 mg/L, pH 8.2), which is great news, but it is important that this continues to fall to zero. All other tests look good, with oxygen levels high (10.1 mg/L, 89 % sat., 9.7 °C).
Today, we stocked 200 very good-looking rainbow trout in Darlow. The lake now contains between 300-400 trout ready for the new season, starting on 01-Mar-2022. We have more fish to follow! The good news is that Darlow has, so far, avoided any unwelcome influxes of flood water, and we hope Read more…
Latest water quality results are showing that conditions are improving. We have a further reduction in levels of total ammonia (0.27 mg/L, pH 8.3, 7.3 °C), and water clarity remains stable. It is also encouraging to see the oxygen levels increasing to similar levels to the river (10.7 mg/L, 90.5 Read more…
The latest water quality tests are showing that total ammonia levels are continuing to fall (0.37 mg/L, pH 8.1, 4.3 °C). This is a very good sign and may be due to the dilution of the water and action of the microorganisms converting it to less toxic nitrite and nitrate Read more…
Happy New Year to you all! The latest water quality tests have been completed and are continuing to show that ammonia levels have stabilised (0.42 mg/L, pH 8.1, 9.7 °C), even slightly declining, which would be fantastic news. Oxygen levels are good, and are now close to matching those in Read more…
Ammonia levels have begun to stabilise (0.45 mg/L, pH 8.0) and oxygen levels are improving with the falling temperature (9.5 mg/L, 74 % at 4.8 °C). The lake is now open again after chalking, and clarity is dramatically improving with visibility down to 3.5 m using the Secchi disc – Read more…
The last water tests before the chalking have shown that oxygen levels look like they are increasing significantly (8.9 mg/L at 73 % saturation). This is a really good sign and may be linked to the reduction in suspended organic matter in the lake. Ammonia level are still increasing, but Read more…
As last week, no major improvement in conditions to report. Ammonia has increased to 0.46 mg/L, at a pH 7.7 and temperature of 9.0 °C, the rate of increase was lower than previous weeks. Water clarity has continued to improved. Testing next week will be carried out later due to Read more…
