Algal Blooms
We’ve had our second algal bloom this year which is unusual so early in the season. The latest has been quite extensive and long lasting turning the water a green brown colour with a distinc-tive “stagnant “odour.

Fortunately, the cooler weather and high rainfall has not caused problems with the fish. These blooms occur in the pond when the nutrient levels are high, and the weather conditions promote water disturbance.

High winds and heavy rainfall churn up silt, nutrients and algal spores from the bottom of the pond triggering growth as day length increases. Nutrient levels may be higher than normal due to the large groups of pink footed geese visiting the pond recently - a group of 15 have been spotted!

These birds will make a significant contribution to the nutrient levels of the pond even if they only visit for a short time when combined with our large resident population of ducks and fish.

Decomposing bread in the water also promotes algal growth so please continue to feed grain instead.

A potentially serious impact of an algal bloom is the risk of an "algae crash" triggered by temperature or barometric pressure. When an algal bloom collapses, dead algae cells settle to the bottom of the pond adding to the decomposing sediment's oxygen demand. If the crash is severe, the pond's oxygen supply can be quickly depleted, endan-gering the fish and other aquatic species.

The reeds planted around the margins of the pond will help to de-crease the nutrient levels in the pond, but the variable weather has slowed their growth so far. Let’s hope the weather settles and the situation improves soon.

If you would like to help as a pond volunteer please contact Alyson on Tel:634 168.

Pond levels are constantly monitored for signs of make-up water and losses.

The Parish Council have agreed to contact ERYC about the large inlet drain at Waters Edge (which may have a leak) and Yorkshire Water with queries about the location of pipes and leakages.
