Bonanza Valley Groundwater Management Area (GWMA)

Groundwater use is vital to the people and economy in the Bonanza Valley. DNR wants individuals, communities and businesses to keep using groundwater. However, groundwater use in the Bonanza Valley might not be sustainable because groundwater use might be having a negative impact on aquifers, lakes, streams or wetlands.

The DNR designated this area as the Bonanza Valley Groundwater Management Area (GWMA) in 2016. The DNR has since increased monitoring, prepared for groundwater flow analyses, and developed a plan.

Action Plan

The Bonanza Valley Groundwater Management Area Plan lays out five broad objectives and describes specific actions the DNR will take. An important focus is to continue collecting and analyzing information to determine whether total permitted groundwater use is or is not having a negative impact on aquifers, lakes, streams or wetlands.

The plan was developed over two years by DNR staff and an advisory team of nearly two dozen representatives of local government, industry, agriculture and other agencies.

The DNR will continue to work with individuals, communities and businesses as we make this determination and as we implement this 5 year action plan.

DNR Objectives

Aquifers, Ecosystems and Surface Waters

Groundwater use in the GWMA does not harm aquifers and ecosystems, and does not negatively impact surface waters.

  • The DNR will improve monitoring of groundwater levels, basin water levels, stream flows, climate; groundwater associated biological communities and water use within the GWMA to inform the DNR permit decisions.
  • The DNR will continue to build a comprehensive hydrological and climate monitoring system for the GWMA. The DNR will coordinate with federal, state, and local agencies in these efforts.
  • The DNR will continue to improve information on water use within the GWMA.
  • The DNR will develop and apply sustainability limits for aquifers, ecosystems and surface waters in the GWMA.
  • The DNR groundwater appropriation permits will integrate sustainability limits, individual and cumulative permit analysis, and will include evaluation of existing permits within the GWMA.
  • The DNR will communicate the status of Objective 1.
  • The DNR will improve access to data collected and analyzed by other organizations in the GWMA.
  • The DNR will promote groundwater recharge in the GWMA, consistent with sound water quality management.

Water Conservation

Groundwater use in the GWMA is reasonable, efficient, and complies with water conservation requirements.

  • The DNR will ensure that groundwater users are complying with water conservation requirements in their water supply plans and permits.
  • The DNR will improve communication about and promote the values of water conservation in the GWMA.

Water Quality

Groundwater use in the GWMA does not degrade water quality.

  • The DNR will include compliance with local, state, and federal water quality regulations as permit conditions.
  • The DNR will ensure that permitted appropriations do not degrade water quality by moving known contaminants.

Well Interferences and Water Use Conflicts

Groundwater use in the GWMA does not create unresolved well interferences or water use conflicts.

Groundwater Permits

All groundwater users in the GWMA have the necessary permits to use groundwater.

  • The DNR will improve its capacity to detect unpermitted groundwater use.
  • The DNR will ensure that permitted volumes reflect actual use and use does not exceed permitted volumes.
  • The DNR will ensure that water users comply with conditions on appropriation permits.
