As outlined in the report 'Open Bay Creek Watershed Assessment, January 2007', author L. M. Bowles, Open Bay Creek suffers from a surplus of sediments deposited from several of its upper tributaries, most notably tributaries 3 and 4 in the creek's most upper reach 4.
Remedial sediment control work was begun on this tributary in 2008 with additional cross ditching within the deactivated forestry 'Seymour Trail' road above Granite Bay Rd. Sediment is still moving through the upper portions of this tributary with more works planned however the immediate installation of a sediment collection site, or large 'sump hole' at the base of the steep gradient area appears to be the most time-efficient means to reduce further deposition within the Open Bay Cr. mainstem.
A sediment collection pond, measuring approx.11x21m, was therefore constructed on Sept.23-25, 2009. Excavation, rock placement and creation of an access road work was done by Benner Forestry Ltd., the woodlot licensee of the site, with supervision by L. M. Bowles.
