9. Non-tidal Network Sampling Changes Since 2011 5 Primary sites initiated. 2 Secondary sites, Accotink Creek and the Rivanna River, changed from secondary sites to primary sites. Implemented Equal Width Depth Integrated sampling on remaining 3 secondary sites.

10. 2012 Challenges DEQ Staffing level reductions in several regional offices. Not hiring field staff replacements. Decreased funding/staff will result in a reduction of gages VADEQ will be able to maintain. New gage required at proposed new network site (primary). Upgrade 4 stations from secondary to primary site. As we expand our NTNW the coordination of storm targeted sampling of the small watersheds may pose significant challenges due to their flashy nature and the need to mobilize quickly.

11. Funding Sources Existing State funding level seems mostly stable (staff attrition and general “hiring freeze” at DEQ is problem) Hopeful for increased funding from EPA beginning 7/1/2012 1 new network station (primary station) Upgrade 4 secondary sites to primary Possible increased future USGS Joint funding for program enhancements
