rederick County recently released the findings of an important study on the health and vitality of its many streams. The survey provides detailed information on the water quality, physical condition and biological activity in the county’s smaller waterways. Two hundred specific sites were sampled for the study. While the news is somewhat mixed, there is plenty of cause for concern. More than half of the county’s stream miles had banks that were either moderately or severely eroded. Nearly 20 percent had badly degraded habitats where aquatic creatures should be found in abundance; 11 of 20 watershed areas in the study received a poor rating for insect life, an important indicator of stream health. As could have been predicted, streams in agricultural areas or in proximity to development fared worse than those more removed from human activity. It’s no secret that runoff from farming and development contribute to stream pollution, sediment buildup and bank erosion.
