Nitrate Challenges

Join us on March 5, 2021 for the Nebraska Virtual Green Infrastructure Tour!  We will re-visit communities across Nebraska to higlight green infrastructure projects and programs, both large and small.

The Upper North Platte River watershed headwaters is located in north-central Colorado, close to Walden, CO. The Sierra Madre mountain range is on the west side of the headwaters and the Snowy Range mountain range is on the east side. Snowmelt from both of these mountain ranges together contribute approximately 75 percent of the water flow in the North Platte River. The fires’ effect on water supplies in the coming years will depend on the amount of snow fall and snowpack received in the watershed during the winter and early spring. There may be slightly higher incidences of sediment runoff in isolated areas where there is little or no ground cover due to the fire.

Join us on November 20, 2020 for the Nebraska Virtual Green Infrastructure Tour!  After 12 years of face-to-face green infrastructure tours, we will take a diversion this year and jump on the virtual tour bus!

A dip in the lake can be refreshing, but it’s important to consider what’s going on in the water that you may not see – especially for E. coli bacteria. Identifying an E.coli issue It’s fairly easy to see Harmful Algal Blooms (HABs) and algae at a lake.  Unfortunately, the same visual assessment does not apply to E. coli.  However, there are three indicators of E. coli in a lake to consider:

Have you ever wondered why groundwater nitrate maps show so much variation across Nebraska? Or why wells near to your own tested well have such different nitrate levels? The answer has three parts. Nitrate in groundwater varies from place to place because of differences in:

The City of Auburn, population 3,000, is located in southeast Nebraska, near the Little Nemaha River, approximately seven miles upstream of its confluence with the Missouri River. The City receives its drinking water from a wellfield located east of the community within an alluvial aquifer along the Little Nemaha River. The wellfield consists of 11 vertical wells averaging 45 to 50 feet below the ground's surface, pumping up to 150 million gallons per year.

Boating season is once again upon us and it is time to remember to clean, drain and dry watercrafts, angling equipment and any other items that come in contact with a waterbody between uses.  Zebra mussels, an invasive small mussel species, can live out of water for up to 2 weeks in the summer time in the right conditions and cleaning, draining and drying watercrafts and equipment for at least 5 days before launching in a different waterbody is pertinent.  Currently there is no effective way to eliminate 100% of zebra mussels from a waterbody so prevention is key. 

Lakes are classified in a number of ways to help us understand how they function, make predictions, assess ecosystem health, and establish management strategies or regulations.  They are most commonly classified by the lake’s ability to support plant and animal life, or productivity. They can also be classified based on the water supply, how humans use them, plant and animal communities, or how they were formed (e.g.  glacier retreating, volcanic eruption, made by man).

Rivers and streams are complex. They are filled with a dizzying array of life, from relatively simple bacteria and algae to more complex forms such as plants, insects, and fish. When everything is working well, rivers provide many benefits to society, including fishing and other recreation opportunities, drinking water, irrigation, and transportation. However, there are also many ways that people can disrupt the natural functioning of rivers. For example, it may be necessary for cities to build systems that rapidly remove rain water to prevent flooding damage to homes and businesses.

Nonpoint source or runoff pollution is harmful to the water quality of our lakes, ponds, and streams. Many of our daily activities contribute to runoff pollution leaving our property and harming our lakes, ponds, and streams. Water quality protection practices help to reduce runoff pollution and protect our water resources.

Everyone lives in a watershed. A watershed is the land area that contributes water to a location, usually a stream, pond, lake or river. Everything that we do on the surface of our watershed impacts the water quality of our streams, wetlands, ponds, lakes and rivers. What happens in one locality affects other downstream areas.
