Algal bloom had been a problem in the Paphayom canal for many years that may affect the lake’s biodiversity. In order to assess the status of the lake, the lake’s plankton and water quality were examined during the study period from June to August 2004. We collected samples from 6 different stations (2 from upstream, 3 from middlestream, and 1 from downstream) of the lake. Water samples were collected to check the density of plankton in water. Forty nine species belonging to 7 different classes were identified including Dinophytes, Cyanophytes, Baccilariophytes, Chlorophytes, Cryptophytes, Euglenophytes and Crysophytes. Temperature, pH, dissolved oxygen (DO), nitrate, and conductivity of water were also checked and recorded. Results showed that, turbidity and nitrate levels did not differ among the stations or streams, but temperature was lower in upperstream than in middle and downstream. On the other hand, dissolved oxygen was lower in downstream than in upper and middlestream. pH also differed among the stations. Density of plankton was negatively correlated with temperature but positively correlated with turbidity and nitrate levels in water.

What is the purpose of this study?
Answer:
1. To study some physical (Tempeature, Turbidity) chemical (pH, DO, nitrate) and small animals in the upstream, middlestream and downstream areas of Paphayom canal
2. To Identify the small animals in the water
3. To make relationships between density of the small animals and water qualities

What are the recommendations?
Answer:
The results of this research will make students and communities more aware of the importance of water resources. This will be a guideline for community water management.

Thank you for this extensive survey of the water quality in Paphayom Canal. Your observations are wonderfully thorough and your bibliography very good.

What have you learned by doing this survey?

Is there a data table of the phytoplankton type observations at the different sites?

If you were guiding an effort to improve water quality in the canal, what would you recommend as the most effective change that could be made?

4. What have you learned by doing this survey?
Answer:
According to the results, tends of water quality at Paphayom flow can use freshwater animals and zooplankton to a biological indicator of water quality. But our collection, we can not determined that small animals and what kind of spawn is the best indicator. Because sampling time can not cover all seasons. we know that downstream water quality is likely to deteriorate. However, the results of this research will make students and communities more aware of the importance of water resources. This will be a guideline for community water management.
5. Is there a data table of the phytoplankton type observations at the different sites?
Answer:
We collected the phytoplankton type at the different sites but we don’t show in the report.
6. If you were guiding an effort to improve water quality in the canal, what would you recommend as the most effective change that could be made?
Answer:
Water quality in Paphayom flow is caused by the use of land on the upstream area. Middle and downstream Water has many contaminants from agricultural areas, pesticides and water from the community. Government agencies must educate the public about wastewater treatment before releasing it to nature and reducing the use of chemicals in agricultural areas.
