How Do Dams Affect Fish and Water Quality?

Although there are many factors impacting urban stream systems from pollution to stormwater runoff to structures in the floodplains, dams create a host of problems for stream systems everywhere. What Did the Fish Say When It Swam Into the Wall? First and foremost, dams fragment stream systems preventing fish from freely move upstream. Even a low-head dam can create a barrier to our midwestern fish, that unlike salmon are not built to jump any significant height. These barriers block access…

Managing Detention Basins for Healthy Communities

Detention basins provide protection from flooding by capturing rain water through a series of storm sewers, holding the water for a specifically designed amount of time and then slowly releasing the water into a nearby stream. When managed well, detention basins not only address water quantity issues, but also water quality issues. A naturalized detention basin – one with native plants around the edges instead of the traditional riprap or rocks, can help: Minimize erosion around the edges, therefore not…

Healthy Rivers and Streams Have More Than Just Clean Water

How healthy is your local stream, lake or pond? Finding the answer requires looking at the three major components of water quality: chemical, physical and biological. Chemical is the one that most people think of when you talk about water quality – how much of a particular pollutant is in the water? But the biology, the critters that live there like fish, insects and mussels, and the physical habitat, like riffles and pools in streams or differing depths in a…

Maintain Your Lawn to Protect Rivers and Streams

Many people like the look of a neatly mowed, bright green lawn. Plus, many communities and Home Owners Associations require residents to maintain their lawns to a certain standard. Traditional lawn maintenance depends on regular mowing, watering and chemical applications—most notably, fertilizers. Lawn fertilizer contains nutrients, such as nitrogen and phosphorous, that encourage turfgrass to grow quickly. However, the fertilizer we put on our lawns also affects the health of our local rivers and streams. What Lawn Fertilizer Does to…

Travels of a Raindrop

How Stormwater Runoff Pollutes Our Rivers A raindrop that falls from the sky needs to go somewhere. When a raindrop cannot soak into the soil, it instead travels across the ground and becomes stormwater runoff. As it flows across the landscape, the raindrop picks up whatever it comes in contact with, such as pet waste, fertilizer, pesticides, road salt, oil from cars, trash and soil particles. The runoff is eventually channeled into storm drains that connect directly to rivers and…
