Document Description
DWR Staff will be repairing erosions at Dyer Dam at Mile Marker 3.7. A backhoe and hand tools will be used to excavate the erosion site to remove any existing gravel or soil with poor structure around an existing culvert and placed at the Dyer spoil pile along the SBA. The culvert will be removed or repaired depending on its condition once it is exposed. Soil around the excavation will be compacted and prepared for backfill with an estimated 10 cubic yards of base rock. A water truck will be used to wet soils during compaction and for dust mitigation. Staging and access will be via existing DWR access roads and improved lots. All work is within DWR right of way.
