A narcotics task force revealed the discovery of 25,000 marijuana plants in North County on Tuesday.
An official with the Drug Enforcement Administration said agents began conducting a marijuana eradication operation on Tuesday in the area of state routes 76 and 79 on the Santa Ysabel Indian Reservation. The official said the drugs have an estimated street value of $75 million to $100 million.
The Santa Ysabel growing operation was the second-largest marijuana field DEA/Narcotics Task Force agents found this year in San Diego County, according to DEA officials.
Authorities said water was being diverted from natural springs in order to irrigate the marijuana and that chemicals were found on the scene, as well as a camp for the people who were tending the plants. It's estimated that four to five people were staying at the location, according to the DEA.
No arrests have yet been made, according to DEA spokeswoman Amy Roderick.
