Cyanobacteria in Brooklands Lake

John Clark made this Freedom of Information request to Worthing Borough Council

This request has been closed to new correspondence from the public body. Contact us if you think it ought be re-opened.

The request was partially successful.

Dear Worthing Borough Council,

3 Jan 2001
Southern Water let sewage from its treatment works swamped gardens and Brooklands Boating Lake. Details in link bellow.

A few months later black lumps of algae rose to the surface of the lake and Birds, Mammals and Fish began to die Details in link bellow.

Last year sewage again found its way into the Brooklands Boating Lake and a few months later, Birds, Mammals and Fish began to die.
Identicle with 2001, black lumps of algae rose to the surface.

The Algae “lumps are collonies that are very dark green and the main component Cyanobacteria (Blue Green Algae) called Oscillatoria.

Eventually the Enviroment Agency identified the presence of Cyanobacteria and appropriate warning was given to the public.

Cyanobacteria can produce toxins similar to BOTAX which paralyse the victim which either falls over and drowns or starves to death. This condition is known as Botulism or Flaccid Paralysis.

Growth of Cyanobacteria is encouraged by high levels of Nitrogen and Phosphorus in the water.

1, Was your organisation involved in testing the levels of Nitrogen or Phosphorus?

2. Does your organisation have any recommendations for testing for or reducing the Nitrogen or Phosphorus in river water?

The growth of Cyanobacteria is promoted by very slow moving of stagnant water.
Brooklands Lake is also part of the Teville Stream, which is an Environment Agency “Main River”

At present the flow of water through Brooklands Lake is very slow because culverts through which the stream should be flowing are completely blocked and water is only flowing from a tributary called the River Ditch.

3. Can your organisation proved me with any information (maps reports etc) as to where the Culverts are that carry the Teville Stream from Davison High School Field to where the River Ditch joins it in the Chesswood Farm Allotment Gardens.
4. Can your organisation proved me with any information as to how the riparian owner can be identified and encouraged to make sure that the passage of water through culvers on his/her land is not impeded.

Ecologically the Teville Stream catchment is in a very poor state. In particular the River Ditch has Japanese Knotweed and Giant Hogweed growing on its banks and if not controlled, these will soon invade the down stream Brooklands Park and Children’s Play Area.

5. Can your organisation provide any guidance or support on this topic?

Yours faithfully,
John Clark

Information.officer, Worthing Borough Council

Information.officer, Worthing Borough Council

Dear Mr Clark,

 

In relation to your questions raised, please see Worthing Borough Councils
answers in red.

 

1.    Was your organisation involved in testing the levels of Nitrogen or
Phosphorus? Worthing Borough Council were not involved in testing the
levels of Nitrogen or Phosporus because Southern Water Services are
responsible for maintaining the water.

 

2.    Does your organisation have any recommendations for testing for or
reducing the Nitrogen or Phosphorus in river water? Worthing Borough
Council does not have any recommendations because Southern Water Services
are responsible for maintaining the water.

 

The growth of Cyanobacteria is promoted by very slow moving of stagnant
water. Brooklands Lake is also part of the Teville Stream, which is an
Environment Agency “Main River”

 

At present the flow of water through Brooklands Lake is very slow because
culverts through which the stream should be flowing are completely blocked
and water is only flowing from a tributary called the River Ditch.

 

3.    Can your organisation proved me with any information (maps reports
etc) as to where the Culverts are that carry the Teville Stream from
Davison High School Field to where the River Ditch joins it in the
Chesswood Farm Allotment Gardens.

 

Worthing Borough Council are responsible for keeping the bed and banks
clear of any matter that could cause an obstruction, either on their land
or by being washed away by high flow to obstruct a structure downstream.

 

Worthing Borough Council are responsible for keeping clear any structures
that we own such as culverts, trash screens.  There are five of these
under our control on the Teville Main River.

 

Please note that I am currently still collating a map which will be sent
to you under separate cover.

 

4. Can your organisation proved me with any information as to how the
riparian owner can be identified and encouraged to make sure that the
passage of water through culvers on his/her land is not impeded.

 

Worthing Borough Council in their capacity as both the landowner and as
Riparian Owner of both the lake and stream has obligations for the
maintenance of the banks and outfall.

 

It manages these roles along with the provision of the lake as a leisure
lake and sometimes these two obligations conflict.

 

 

Ecologically the Teville Stream catchment is in a very poor state.  In
particular the River Ditch has Japanese Knotweed and Giant Hogweed growing
on its banks and if not controlled, these will soon invade the down stream
Brooklands Park and Children’s Play Area.

 

5. Can your organisation provide any guidance or support on this topic?

 

I confirm that the maintenance carried out as follows:

 

•           04/2005 Supplied and installed piling to banks together with
other general reactive repairs as necessary.

•           05/2006 Supplied and installed piling to banks together with
other general reactive repairs as necessary.

•           06/2007 Lining of voids to the bank with appropriate

•           07/2008 General bank and drainage system repairs together with
other general reactive repairs as necessary.

•           08/2009 General drain repairs and purchase of timber for

railing, repairs to spillway and general reactive repairs as necessary.

•           12/2012 General bank repairs, installation of new bench,
repair to gabions and piling design for new steel sheet piled section
between the bridges together with other general reactive repairs as
necessary.

•           Current year Grill/screen clearance.

 

 

I trust this information has been of assistance to you.

 

Yours sincerely,

Dear Mr Clark,

 

May I send you my sincere apologies for the delay in coming back to you
regarding this matter.

 

Regrettably, the maps are not available via the internet on the Councils’
webpage.

 

I confirm public sewer maps provided by Southern Water are available and
can be viewed by members of the public at the Help Point in Portland
House, Richmond Road.

 

I trust this has been of assistance to you.

 

Yours sincerely,
