Pond Partnership (SPP)
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!
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
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.
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
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.
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
