The bright red dots are where
Cutrine Plus, Cutrine Ultra, and
Captain (copper-based herbicides) are dripped
directly into the water monthly during the irrigation season, between April - October.
To know when drip applications are taking place, visit NID's 2019 Aquatic Weed Control Schedule.
All canals are in blue, the sections highlighted in dark red are "randoms" which are natural drainages that were captured and incorporated into the canal system.

NID uses a multitude of terrestrial herbicides throughout the district along irrigation canals.
During the irrigation season (April 15th - October 15th), Roundup Custom is one of the primary terrestrial herbicides used to control the weeds along irrigation ditches, maintaining NID's "bare ground herbicide program."
During the off-irrigation season, Roundup Custom and other herbicides are used inside berms and de-watered canals.
#1 Unlike aquatic herbicides, NID does not inform the public or water users before terrestrial applications
#2 Applications may expose people, pets, wildlife, livestock, organic agriculture, and more to herbicides
#3 Recent court cases & research studies indicate Roundup exposure may cause negative health impacts across generations
