Grants Pass TMDL Homepage

Program Summary

To meet the requirements of the Rogue Basin TMDL under the Clean Water Act, the City of Grants Pass is implementing management strategies to improve water quality conditions by reducing or eliminating temperature and bacteria inputs within the City limits and Urban Growth Boundary to the Rogue River and its tributaries (e.g., Gilbert Creek, Sand Creek).   Strategies include riparian restoration to improve stream shade, managing urban runoff, community education and outreach, and erosion prevention and sediment control.   Planned strategies are outlined in a DEQ approved plan that is  implemented over a 5-year period.   After 5-years, plans are revised and updated for another 5-year period until water quality standards are met.

Plan years run from July 1st through June 30th annually.   The first 5-year cycle ran from July 1st, 2010 through June 30th, 2015. Revised plans for the next 5 year implementation period (2015-2020) were submitted to DEQ for approval in June 2015.   Grants Pass began implementation of the new plan on July 1st, 2015.

  • Year 8/3- July 1st, 2017 through June 30th 2018 (Current Year).
  • Year 7/2- July 1st, 2016 through June 30th, 2017.  Previous Year.  Reports due on September 30th, 2017.
