Management Areas

The Little Blue NRD’s philosophy regarding groundwater problems is that prevention is less costly than correction. Therefore, the district has adopted programs that emphasize proactive protection of groundwater, rather than a reactive, corrective approach. Since the early 90’s, the district has been monitoring nitrate levels across the district. In certain areas of the district nitrate levels have already exceeded the health standard of 10 parts per million and in other areas contamination seems to be on the rise.

The entire District was declared a Water Quality Level I ManagementArea on July 1, 1996, which emphasizes education on water and fertilizer management. When sampling results show 70% of MCL has been reached for any sampled water constituent in 60% or more of at least 5 sampled wells within an area, the NRD board will take actions to further identify the problem area, establish sub-area boundaries and determine the controls to be implemented.

The purpose of establishing a sub-area is to focus management efforts and education in an attempt to isolate, halt and/or reverse contaminant trends. A sub-area for Quality controls is defined as an area containing at least five sampled wells within the LBNRD’s well sampling program around which a logical and necessary boundary can be drawn. The minimum size of a sub-area, of which LBNRD currently has eight, is 16 square miles.

Wellhead Protection

The Little Blue NRD voluntarily works with communities to provide the information and education needed in the development and maintenance of a Wellhead Protection Area. Services that can be provided to a community interested in a Wellhead Protection Area are:

  • Voluntary training sessions on water management techniques, pumping plant efficiency new technologies and research, fertilizer management, etc.
  • Encourage the use of BMP’s as listed in the District Groundwater Management Plan.
  • Sponsor and participate in demonstration projects.
  • Provide public information and education programs through newsletters, articles, pamphlets, TV, radio, magazine or public forums.
  • Establish water conservation, lawn care and management programs in cooperation with cities and villages.
  • Provide technical assistance in developing efficient irrigation systems and management schemes.
  • Offer in-house nitrate analysis with Hach Spectrophotometer.
  • Maintain an ongoing program of sampling wells for groundwater quality throughout the area. Identify any obvious sources of pollution.
  • Cost share assistance on well decommissioning, soil sampling, irrigation management, buffer strips, nutrient management and trees
  • Establish controls and program requirements for new water wells, well abandonment, chemigation and sharing of information with various agencies.

Residents of cities and villages should contact their local city office to inquire about any nitrate questions you may have.

 

Irrigation Scheduling

Assistance with irrigation management from the Little Blue NRD and  DarylNebraska Extension Service is a result of the Irrigation Scheduling Program. Area farmers have altered their irrigation scheduling to save money and water. The project is an extension of NAWMDN (Nebraska Ag Water Management Demonstration Network) whose goal is to assist the producer in knowing when to start and stop irrigating for the season sensors

Equipment used is an ET (evapotranspiration) gauge and three soil moisture sensors per field which are placed at 1, 2 and 3 foot intervals as shown by the photo. This equipment measures the amount of water available in the soil that the crop can utilize. The majority of producers utilizing these tools have held off irriation until July 1st.

The District offers equipment for this program to residents at a reduced rate. Contact the Little Blue NRD office for more information.
