http://environment.data.gov.uk/data/bathing-water-profile/ukf1400-09750/2024:1

  • bathing water description
    West Lake is located within the south west corner of Colwick Country Park, Nottingham formed originally from gravel workings. Access to the swimming area is via a floating pontoon or a concrete slipway next to the adventure centre. There is no beach but there is a grassy area around the lake. West Lake is also a coarse fishery and is used for canoeing and sailing by the adventure centre.

  • eso outfalls statement
    There are no overflows from the sewerage system into West Lake.
  • history statement
    Water company assets are not considered to pose any risk to the bathing water quality of West Lake.
  • local authority statement
    There are no surface water drains that discharge into West Lake. Nottingham City Council also undertakes fortnightly testing for blue-green algae.
  • misconnections statement
    Modern sewerage systems have two separate systems, one takes foul sewage to sewage treatment, the other takes rainwater runoff through surface water drains to rivers, lakes and the sea. Misconnections occur when waste water pipes are plumbed into surface water drains instead of the foul water sewerage system. This can give rise to pollution when the waste water is discharged directly to the environment through the surface water drain. For example, a washing machine or toilet may be incorrectly plumbed so that it discharges to the surface drain rather than the foul sewage drain.
  • phytoplankton statement
    For the four year (2020-2023) assessment period where data is available, phytoplankton (microscopic algae) was assessed as being sufficient to be objectionable for 20% of visits, with 49% of visits noting the presence of phytoplankton (microscopic algae). Phytoplankton (microscopic algae) increase in number at certain times of the year. This process is known as a phytoplankton bloom. Blooms of phytoplankton can result in the water appearing discoloured or a foam forming on the water. TheEnvironment Agency research suggests this bathing water has a history of phytoplankton blooms. If a bloom of blue-green algae is visible you are advised not to enter the water and to contact the bathing water operator.
  • pollution risk forecast statement
    There are no active pollution risk forecasts made at this bathing water. However any bathing water has the potential to be affected by a pollution incident and if this occurs a pollution risk warning with associated advice against bathing will be issued on this website.

  • visible pollution statement
    Environment Agency samplers make observations of litter present on the beach at every visit, this includes assessments of sewage debris, litter and tar. At Colwick Country Park (West Lake) for the four year (2020-2023) assessment period where data is available, sewage debris was not noted at this site. Litter was assessed as being sufficient to be objectionable for 2% of visits, with 80% of visits noting the presence of litter. Tarry residue was not noted at this site.
  • working with private owners statement
    The Environment Agency work with the bathing water operator to investigate and remediate any bathing water quality failures at West Lake.
  • zoi description
    The catchment is predominantly parkland consisting of woods and grassland and is adjacent to the River Trent, it receives rainwater runoff from the parkland surrounding it.

    • algae general statement
      Seaweed (macroalgae) and phytoplankton (microscopic algae) are a natural part of the marine and freshwater environment. Below we note whether these have been recorded in quantities sufficient to be a nuisance.
    • eso outfalls general statement
      The majority of sewers in England are “combined sewers” and carry both sewage and surface water from roofs and drains. A storm overflow operates during heavy rainfall when the sewerage system becomes overwhelmed by the amount of surface water. The overflow prevents sewage from backing up pipes and flooding properties and gardens. An emergency overflow will only operate infrequently, for example due to pump failure or blockage in the sewerage system.
    • local authority general statement
      Heavy rain falling on pavements and roads often flows into surface water drains or highway drains, ending up in local rivers and ultimately the sea. The quality of bathing water may be adversely affected as a result of such events.
    • pollution management general statement
      It is the Environment Agency role to drive improvement of water quality at bathing waters that are at risk of failing higher standards. It is natural for water to run off the land to the sea. Water quality at a bathing water is dependent upon the type and area of land (the catchment) draining to the water and the activities undertaken in that catchment.
    • stw outfalls general statement
      Discharges from sewage treatment works have improved substantially in England since the 1980s.
