Stillwaters monitoring programme.Summary results 2003 and 2004

This is the Stillwaters monitoring programme. Summary results 2003 and 2004 from the Environment Agency North West. This report is focuses in The Winter Monitoring of Stillwaters Programme, which began in January 2001 with the aim of gathering long term data on nutrient abundance over winter months. This allows assessment of nutrient ‘carry-over’ available for algal growth in the following year, plus year-on-year productivity. 14 stillwaters are monitored each year. The environmental issues associated with each Stillwater are summarised in the table below. Bank-side water samples are taken for nutrients (N, P and S) and chlorophyll. A YSI multi-parameter sonde measures temperature, pH, specific conductivity and dissolved oxygen (% saturation). Survey results shown in this report came from: Oak Mere and Bar mere.

Stillwaters monitoring programme. Summary results 2004 and 2005

This is the Stillwaters monitoring programme. Summary results 2004 and 2005 from the Environment Agency North West. This report focuses on the 5th year of winter monitoring analysis in 14 stillwaters in Cheshire. The 14 stillwaters analysed are: Comber Mere, Oss Mere, Marbury Big Mere, Chapel Mere, Bar Mere, Oak Mere, Hatch Mere, Black Lake, Betley Mere, Tabley Mere, Melchett Mere, Tatton Mere, Rostherne Mere and Mere mere. Nutrient availability in the stillwaters analysed is used to look into the productivity of the waterbody. Bank-side water samples were taken for nutrients (Nitrogen and Phosphorous) and chlorophyll. A YSI multi-parameter sonde measures temperature, pH, specific conductivity and dissolved oxygen (% saturation).
