Upcoming Drainage Hearings or Meetings:
We Minnesotans know just how challenging getting around can be in the winter. We rely on our snow plow crews to keep our roads clean and safe for travel. Part of keeping our roads safe for travel in Minnesota includes the use of salt on our roads, parking lots, and sidewalks. With the very large emphasis on water quality in our state, we need to consider the ill effects from using salt around our freshwater lakes, ponds, rivers and streams.
One teaspoon of salt can permanently pollute five gallons of water. We use hundreds of thousands of tons of salt across the state. The salt we use for keeping the ice off our roads, parking lots, and sidewalks contains chloride. Chloride is finding its way into almost all major waterways across the state. The salty, chlorinated water is having noticeable affects on fish populations and other aquatic species.
Currently there are no environmentally safe or inexpensive alternatives to using salt. There are however smart salting strategies to help reduce salt usage. Thinly and properly spread salt has the same melting capacities as large, heavily spread amounts. Twelve ounces of properly spread salt should melt around 1,000 square foot area. Salt isn’t the only answer to ice. Salt actually is non-effective below 15 degrees Fahrenheit. Manual or mechanical means of snow and ice removal is a better choice. If there is the need to use salt, use it sparingly and spread as even as possible to reduce any future damage to our waterways and aquatic ecosystems.

We require that all repairs to a county drainage system (tile or open ditch) be authorized by one us in the drainage office, either Craig or myself, before any repairs are made.
