Monitoring for 2019
Thiobencarb monitoring starts at the Colusa Basin Drain 5 (CBD5) on Tuesday – the typical start date of water quality monitoring. The CBD5 site is off Highway 20 in Colusa County, and receives drainage from both Colusa and Glenn Counties. The Colusa County Agricultural Commissioner’s office announced receipt of the first thiobencarb notice of intent (NOI) with applications under way. Confirmation of intent to apply thiobencarb from the other rice counties will trigger the decision to add in the remaining monitoring sites. We estimate this will happen as early as May 7.
