John Sutton, who previously worked for the EA (and is now a professional photographer), writes:

“Last year on 14th September, Wild Oxfordshire, the Freshwater Habitats Trust and Thames Water, amongst others launched what was probably the first ‘WaterBlitz’ across the River Thames catchment. The intention was to collect as many nitrate and phosphate measurements within a 24 hour period with the help of citizen scientists.

In all, 645 measurements were sampled by individual members of the public, school and community groups and experts alike! In keeping with citizen science this was far more than any single scientist or team of scientists could collect in a day. Find out more about the data through the FreshWater Watch Water Hub.

The benefit of collecting this amount of data within a 24 hour period is that you get a temporally comparable result whether you are on a small tributary of the Lea or on the Thames at Lechlade. At the same time, water quality differences between sites are less likely to represent seasonal or climatic changes that occur throughout the year.

Importantly, they are more likely to highlight underlying issues such as pollution sources. Aside from contributing to the wider FreshWater Watch initiative, data collected in this manner directly compliments regular monitoring carried out by the Centre for Ecology and Hydrology and could help elucidate particularly problematic still and flowing waters (taken from Dr Ian Thornhill’s blog, see here).

Members of Fleet Pond Society (FPS) took part in the April 2016 Water Blitz, sampling a series of waterbodies associated with Fleet Pond. The survey will be repeated in October 2016. See the results in the table below:

These values are expected to vary throughout the year as a result of weather patterns and changes in land use.

What are nitrates and why are they important?

Nitrate (NO3) is a form of nitrogen that is highly soluble in water. It is used in fertilisers and can move readily with surface runoff into rivers. Studies indicate that more than half of the nitrate fertilisers applied to fields can end up accumulating in the soil or running off into surface water and ground water. Other sources of excess nitrates can be traced to human wastes and industrial pollution.

Algae and other plants use nitrates as a source of food and elevated concentrations can create conditions that make it difficult for aquatic fauna, including fish and invertebrates, to survive. This occurs when large amounts of algae cause extreme fluctuations in dissolved oxygen. Photosynthesis by algae and other plants can generate oxygen during the day. However, at night, dissolved oxygen may decrease to dangerously low levels as a result of oxygen consuming bacteria feeding on dead or decaying algae and other plants.

Why is phosphate important?

Phosphates (PO4) can enter aquatic environments from the natural weathering of rocks, from the decomposition of plants, or from human activity such as fertilizer runoff and improperly treated waste-water. Phosphorus is an essential element for plant life, but in high concentrations favours the excessive growth of algae, with negative impacts on the fish and the health of our rivers and lakes.

The input of phosphorus from sewage treatment works to rivers is relatively constant through the year while agricultural inputs are much more closely linked to rainfall events and more seasonal. Efforts to reduce phosphorus coming from wastewater-treatment facilities and the use of phosphorus detergents has led to reductions in phosphate concentrations in European waterbodies, but 45% of rivers in England fail the EU Water Framework Directive for phosphorus standards.”

For completeness, here’s a nice video on the Water Blitz project showing how children can get involved as part of citizen science:



Wates Developments Supports Fleet Pond

June 19, 2016

Wates Community Day 2016 s

Members of the Wates Developments team plus Hart Rangers, together with the product of their efforts!

Emma Gruenbaum, Land & Planning Manager at Wates Developments, writes:

“As part of Wates Group’s annual community day, a 19 strong team from Wates Developments has spent the day clearing unwanted saplings and weeds from an area of heathland at Fleet Pond.

The 141 acre nature reserve is owned by Hart District Council and is managed in partnership between Hart Countryside Service and Fleet Pond Society, a registered charity. In addition to the full day of weeding, the charity will also benefit from a £500 donation made by Wates.

The community day is an integral part of Wates Groups annual charity work and a key fixture in the company’s diary since 2008. Wates Giving is a charitable programme run and funded by the Wates Family Enterprise Trust, set up by the family with the aim of strengthening the role business has to play in society, focused on making a real difference to the communities in which we live, work and build.

Since 2008, Wates Giving has invested over £8m in local initiatives through five themes: Education; Employment and Training; Social Enterprise; Sustainability; and Community Building. Wates Group has twice won the Queen’s Enterprise Award and remains the only construction company to have won.”

Fleet Pond Society is very grateful to Wates Developments for providing the large volunteer team as well as the very generous donation.

Volunteer Event This Sunday, 12 June

June 8, 2016

There will be a volunteer event at Fleet Pond this coming Sunday and all are welcome to attend (see below for registering).

Colin Gray, Chairman of Fleet Pond Society, writes:

“On Sunday we will be doing some more repairs to the banks of the Gelvert Stream.

Please assemble at the Countryside Workshop, Old Pump House Close, Fleet, GU51 3DN at 9.00 a.m. for a 9.15 start. The nearest access point, if you do not come to the workshop, is Guildford Road.

As usual we will have tea, coffee and chocolate available but please bring your own cold drink. Some volunteers will need wellies and others can work from the bankside.

If this hot rather muggy weather continues, you might be wise to bring insect repellent with you as our mosquitos can get a bit hungry. Those who do not bother with insect repellent can comfort themselves that our bats will enjoy some good, fat mosquitos for supper.”

For further information and booking for this event (which is essential as tools and resources have to be planned beforehand), please contact Hart Countryside Services:

Phone: 01252 623443
 Email: countryside@hart.gov.uk

The Sunday volunteer tasks are supervised by a Hart Countryside Ranger, Nick Macfarlane, together with members of Fleet Pond Society.

Local History Group Celebrates 30 Years

June 7, 2016

Old Map Fleet Pond

A map of the Pondtail area of Fleet in the 1880s donated to Fleet and Crookham Local History Group (see link below)

From Get Hampshire:

Fleet and Crookham Local History Group is 30 years old, having been set up in 1986 following a wish from within the Fleet and Crookham Civic Society to have a museum in Hart.

The archive catalogue lists more than 8,800 items and the scans of material donated or loaned now numbers more than 58,000.

The group is now looking for a secure room in which to store archive material, with additional space for volunteers to work on cataloguing and scanning, and to carry out research and answer enquiries.

In 2007, the group was given a National Lottery award of £3,880 to increase public access.

This included purchase of display stands and providing copies of local history material, such as directories, census returns and topics relating to businesses, sport and graveyard memorials, in a set of red binders on open shelves in Fleet Library.

To widen contact with the public, the group invites enquiries and offers of information at its Meet the Local History Detectives sessions, held in Fleet Library.

The History Group’s web site can be found here.

You can find detailed information on the history of Fleet Pond on the FPS website here.

  • Pipe cleaner dragonflies
  • Bat finger puppets

At the time of writing, the weather is predicted to be warm and sunny 🙂

Please see the poster here that gives full details (how to get to the event etc).

Previous Wildlife Days have proven very popular and to get a flavour, take a look at the photos below, which were taken at last year’s event.

We look forward to seeing you there!


Looking at fish taken from the Pond – some surprisingly big ones!


The Fleet Pond Society stand – we’re there to answer your queries
