Stormwater Management

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

Soil erosion and subsequent sediment delivered to streams and lakes is a serious water quality problem in Nebraska. Sedimentation of small reservoirs reduced flood-holding capacity. High nutrient runoff can lead to harmful algal blooms.

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.

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.

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!

When planning gardens, people may think about pollinators and select plants to benefit them. Another trend is using rain gardens to catch and hold rainwater. Water and pollinator conservation are two goals achieved with rain gardens. Rain gardens reduce irrigation needs and can decrease the amount of rainwater running off of a property and carrying pollutants to surface water. Rainwater is a valuable resource. Consider collecting some of it with a rain garden that is filled with plants to benefit pollinators.

Join us on the 11th annual Omaha Green Infrastructure Tour! This year, we invite you to join us for a Maintenance and Management tour.  We will re-visit some of our most interesting tour stops from the past decade and explore the good, bad and ugly of maintaining and managing green infrastructure.

Flood-soaked grain or hay is almost certain to be contaminated, making it unfit for use as food or feed.  This summary describes regulatory considerations and recommended actions for management of agricultural grains and forages deemed unusable for food or feed following flooding.

When it rains, do you know where rainwater from your property goes? Does it spread out and soak into the lawn or landscape beds to recharge soil moisture and benefit plants; or does it run off into the street and down a storm drain where it often transports pollutants to surface water?

As we move into winter, store lawn and garden pesticides correctly and securely. Read and follow the label for safety and to help prevent accidental poisoning or spills that could contaminate storage areas or water resources.

Freezing temperatures are ending the growing season and its time to do yard and garden cleanup to help reduce overwintering diseases and insects; and to reduce the amount of plant debris washed into streams, lakes, and ponds where they contribute to water pollution.

Storm drains in some towns have markers that read “No dumping. Drains to waterways”.  These markers are part of the public education communities are doing to help protect surface water from urban run-off pollution. Most residential areas are designed for rainwater to flow into the street and then into a storm drain. From there, it flows almost directly to a stream, river or lake, taking along what it picks up from surfaces it flows across.

Rain gardens are an aesthetic feature of your residential landscape that also has a hydrologic function. Hydrologic means related to water. A properly designed and constructed rain garden for a residential landscape (no underground drainage system) is designed like a bathtub to hold water and let it slowly seep into the soil beneath the garden. This water is available for plant growth, and this water is removed from runoff that leaves your yard and does not contribute to downstream flooding or pollution.  How well does your rain garden serve its hydrologic function?

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.

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. 

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.

Join us, as we tour some of the newest stormwater management projects in Omaha and re-visit established green infrastructure projects. Six of this year’s tour stops are new to the tour! Criteria for tour stop selection included ensuring a variety of consultants, various project scales, various management practices, and availability of tour guides. Tour stops will include:

The 2017 Spring Stormwater Symposium brought together professionals from both public and private sectors to learn from local, regional and national experts. The symposium will focused on examples of stormwater program funding and management, and took an in-depth look into the life cycle of a successful stormwater management project.

The stormwater activity sheets below can be downloaded and used with the Stormwater Sleuth comic book or on their own. They are designed for students from 4th - 6th grades, but may be appropriate for other ages as well.

Soil erosion and sediment loss from construction sites has been documented as a major source of water pollution. Bare soil exposed to a rain event can become quickly eroded, leading to sediment that moves into adjacent storm sewers or lakes and streams.
