Welcome to miniSASS
What is miniSASS?
miniSASS is a simple tool which can be used by anyone to monitor the health of a river. You collect a sample of macroinvertebrates (small animals) from the water, and depending on which groups are found, you have a measure of the general river health and water quality in that river.
Anyone can learn how to collect a miniSASS sample on a river. Once you have collected a sample you look for the different bug groups and score whether they were found. The score then tells you the health class of the river, ranging across five categories from natural to very poor.
Have a look at the How To page to see how easy it is. Through miniSASS you can learn about rivers, monitor the water quality of rivers within your community, and explore reasons why the water quality may not be as clean as everyone would like.
The most important feature of the new website is the miniSASS Map, which allows you to explore your catchment, find your river, look at any existing miniSASS results and then upload your own miniSASS results! The map also lets you explore your catchment to see the land uses and activites that might be improving or worsening water quality.
Get your community, school or family and friends involved in monitoring a selection of your streams and rivers. In this way a map of river health across Southern Africa will develop. Communities can use the information and knowledge to illustrate the plight of their rivers, connect with other miniSASS samplers and investigate pollution sources.
