Data

Below is a selected summary of data collected by CWMN volunteers from Fall 2022 – Fall 2024. The ponds span a gradient from low productivity (oligotrophic) to extremely high productivity (hypereutrophic). The bar graphs represent mean concentrations of each parameter, with error bars showing the standard deviation. Numbers shown above the bars indicate the total number of samples used to calculate the mean values. This page shows a sample of ongoing data collection and will update periodically.

Pond data are collected by community members for our community to use!
