Sandpit Lake Basics – Where does the water come from?

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).

Stream Biological Monitoring

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.

Control Broadleaf Weeds in the Fall

Weeds in the lawn will drive us crazy through the whole summer, but don’t forget about them yet. Fall is the best time to treat for broadleaf weeds, even though we don’t notice them as much now because they are done blooming for the year.

Manure Impact on Erosion and Runoff

Manure's ability to improve soil properties can reduce erosion and runoff.

This article reviews the value that results from changes to soil’s physical characteristics. Charles Wortmann and Dan Walters, faculty with the University of Nebraska-Lincoln monitored soil erosion, runoff, and phosphorus (P) loss from replicated field plots over three cropping seasons immediately after manure application and four subsequent years when no manure was applied. Significant erosion and runoff benefits were observed for sites receiving animal manures.

Yeast Additives and Wastewater Lagoons

Additives such as yeast are marketed as a quick and easy way to improve bacterial degradation of the wastewater within a system such as a lagoon. However, the reality is that none of the yeast additives have been proven to be effective in improving bacterial action within your lagoon. Additionally, yeast additives have shown to have negative impacts on groundwater quality as well as potential further negative impact on surrounding environmental resources such as vegetation. If you think the waste treatment is insufficient, consider taking the following two steps:

Monitoring Nebraska’s Public Beaches - Water Quality and Health Alerts at Your Favorite Lake

Have you ever wondered about the water quality in your favorite lake? Or perhaps you’ve planned a day at the lake only to see a sign that says “Health Alert” and not known what that meant.

Manure Impact on Soil Aggregation

The organic matter in manure improves soil quality including formation of stable soil aggregates.

Manure increases formation of larger and more stable soil aggregates. Several benefits result for fields fertilized by manure compared to commercial fertilizer including reduced runoff and soil erosion and increased water infiltration leading to greater drought tolerance.

Harvest the Rain, It's a Precious Resource

Rainwater harvesting treats rainwater as a resource to be collected rather than a waste product to be conveyed away as quickly as possible. Collected rainwater can be diverted to planted areas such as rain gardens for infiltration or temporarily held in a storage device like a rain barrel or cistern for future use.

An Overview of Secondary Aquifers in Nebraska

Map showing the extent of the High Plains Aquifer

Nebraska is a groundwater-rich state. Nebraska has one primary aquifer, the High Plains Aquifer, and seven secondary aquifers. These secondary aquifers supply water to more than 4000 active wells spread across 30 counties.
