Watersheds

As surface/canal water usually curtails mid-September, extension recommends that Nebraska Panhandle producers ensure their soil water profiles are full to sustain crops through to harvest.

Nitrogen is an essential plant nutrient but increasingly found in our water. Here is a brief history:

Featuring the Republican River, which holds the record for the worst flood in Nebraska history.

Part 3 of the Nebraska Rivers series focuses on the Loup River drainage system, which originates in the Sandhills.

Part 2 of a six-part series that will cover the major rivers and their respective drainages found in Nebraska, with some geography and history about Nebraska’s rivers.

This new series by Nebraska Extension Educator Gary Stone highlights the main rivers in Nebraska and their impacts across the Midwest and Northern Plains. Part 1 of a six-part series that will cover the major rivers and their respective drainages found in Nebraska, with some geography and history about Nebraska’s rivers.

This year's conference will focus on innovative ways to improve water and food security by increasing farmers’ resiliency to a changing landscape.

A new Nebraska Extension NebGuide clarifies the concept of consumptive use of water with regard to irrigated crop production and provides guidelines for determining the efficiency of new irrigation technology.

In 2023, the Nebraska Legislature passed LB1014.  This bill took 4 million dollars from the American Rescue Plan Act and allocated it to treating nitrate issues in Nebraska.  1.2 million dollars of that has been dedicated to a Reverse Osmosis Rebate Program that is directed at private well owners. The general idea of the program is that any individual private drinking water well owner can test their water AND if the nitrate concentration comes back above 10 ppm, they might be eligible for UP TO $4,000 support to get a reverse osmosis system to treat their nitrate.

Some crop growers have always removed crop residue for animal feed and bedding. Crop residue removal should be done in such a way that it benefits the grower without negatively impacting the health and productivity of the soil as well as the environment.

Precipitation continued the trend of a general lack of moisture during the first month of fall. Our monthly statewide total came in at 27th driest and makes for the 12th driest three-month (July–September) period on record. At the start of October, nearly all of Nebraska is in a drought category, according to the U.S. Drought Monitor. Portions of the northeast and southwest are in exceptional drought (D4). Temperatures averaged above normal for September and quite a few new daily high temperature records were set, most in the triple digits. The October outlook doesn’t appear to have much relief in sight with a higher-than-average probability of the warmth and dryness to continue. Given the dryness, fire danger will be high particularly on windy days.

Cover crops are a proven method for increasing soil health by reducing soil erosion, increasing soil organic matter, and improving soil structure. Cover crops also have the potential to positively impact water quality by reducing nitrate leaching and nutrient runoff. While cover crops are growing in popularity in Nebraska, there are significant planting challenges. To address these challenges, interseeding has been proposed as an alternative planting method to increase cover crop success.

Part 5 of a six-part series on the dams, reservoirs, power generation and some diversion dams located on the North Platte River. The series will follow a chronological order of the history and construction of these projects.

Part 4 of a six-part series on the dams, reservoirs, power generation and some diversion dams located on the North Platte River. The series will follow a chronological order of the history and construction of these projects.

The first dam and reservoir on the North Platte River after it enters from Colorado is Seminoe. Seminoe dam is part of the Kendrick Project intended to generate hydropower and expand irrigation in central Wyoming. The project, called the Casper-Alcova Project, was authorized in 1933 under the National Recovery Act during the Great Depression. The project was renamed the Kendrick Project in 1937. The Kendrick Project also includes the Alcova dam, reservoir and the Casper-Alcova Canal.

Leading into the sixth year of appropriation shortfalls, Nebraska Mesonet weather stations that are not contracted specifically by clients are slotted for closure to cut costs and reduce labor overhead.

When the Reclamation Act passed by Congress in 1902 and the United States Reclamation Service was created, studies were conducted to determine where water projects could be constructed. Initially, the Sweetwater River (Sweetwater Project) was considered to construct a dam at “Devils Gate” to provide irrigation water. However, insufficient flows in the river did not justify the construction of a dam. The Reclamation Service then determined that a dam would be constructed on the North Platte River in the Fremont Canyon approximately 47 miles southwest of Casper, Wyoming.

The Platte River, then the North Platte River, and then the Sweetwater River were the series of water courses across Nebraska into Wyoming east of the continental divide for a pathway across the country that “followed the water.” This was the most traveled route across the continent for early trappers — the California, Mormon, Oregon, Overland and Pony Express trails. Over 400,000 people followed these trails to California, Oregon and Washington, bypassing the “Great American Desert”, not knowing that in the future — with irrigation water development — this area would be the breadbasket for the country.

This year's theme focuses on "Groundwater: Making the invisible visible" to bring attention to this hidden water resource, that all too often goes unrecognized when sustainable policies are developed.
