The California Department of Boating and Waterways is expected to begin spraying areas in and around Discovery Bay and Bethel Island this week in a series of treatments designed to manage the egeria densia water weed.

Areas to be treated include:

Bethel Island – Taylor Slough, Piper Slough, Dutch Slough and Sand Mound Slough.

Coney Island – Rivers End.

Wright’s Tract – 14 Mile Slough and Village West.

King Island – Honker Cut, White Slough, Disappointment Slough and Bishop Cut.

Lower Jones Tract – Whisky Slough.

Steamboat Slough.

Sycamore Slough.

Orwood Island and Byron Tract – Discovery Bay (west side and portions of the East side, Beaver Bay, Harbor Bay and Indian Bay).

The invasive weed first caught the attention of local homeowners and officials two years ago when it began clogging area bays and waterways up and down the Delta. The Department of Boating and Waterways began spraying areas in Discovery Bay and Bethel Island with the non-toxic chemical fluridone and will use the same treatment plan this time.

Treatment throughout the Sacramento-San Joaquin Delta Region is expected to run through the middle of October. For more information, visit www.dbw.ca.gov or call 888-326-2822.
