Watersheds

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.

Mullen and Cameron Peak Wildfires and Their Potential Effect on Nebraska Ag

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.

Nitrate in Nebraska

From increased water bills to closed lakes to tainted drinking water, high nitrate levels are affecting thousands of Nebraskans. Nitrate can’t be seen or smelled, but it is in Nebraska’s groundwater, which is the source of drinking water for much of the state. Nitrate also contaminates surface water such as streams and lakes.

Understanding Bacteria in Lakes

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:

Why does groundwater nitrate vary so much across Nebraska?

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:
