Project schedule

Item #8

Project Schedule

  • WY 2005

    • Report completed read for review

  • WY 2006 funded by USACE/SCVWD / RMP

    • Complete QAQC for all WYs and get the data on the WWW

    • Write papers for Journal

  • WY 2007 funded?

    • Only WY 2006 currently guaranteed but everything in place for continuation

    • RMP funding not yet discussed

  • Future Modeling (if funding is found)?

    • Explore transport processes in more detail

    • Explore and predict the effects of management on Hg loads
