THE PROJECT WILL BE IMPLEMENTED DURING THE IN-STREAM WORK WINDOW
IDENTIFIED BY THE NATIONAL MARINE FISHERIES SERVICE AND THE U.S. FISH &
WILDLIFE SERVICE DURING THE CONSULTATION PROCESS. THE LOWEST SEASONAL
FLOWS IN THE CROOKED RIVER OCCUR BETWEEN JULY AND SEPTEMBER. MEAN DAILY
FLOW CONDITIONS ARE EXPECTED TO BE 60 CFS IN MID JULY, DROPPING TO 20 CFS BY
SEPTEMBER AND INCREASING TO 30 CFS BY NOVEMBER. DURING THIS TIME, WATER
SURFACE ELEVATIONS ARE EXPECTED TO BE APPROXIMATELY ONE TO TWO FEET
BELOW EXISTING TOP OF CHANNEL BANK ELEVATIONS. FLOW VELOCITIES ARE
EXPECTED TO BE LESS THAN TWO FEET PER SECOND.
FLOW CONDITIONS DURING IN-WATER WORK WINDOW
THE WORK AREA WILL BE ISOLATED FROM FLOWING WATER USING THE PREVIOUSLY
CONSTRUCTED TEMPORARY BYPASS CHANNEL. THE GROUNDWATER TABLE IS HIGH IN
THE CROOKED RIVER VALLEY AND IT IS EXPECTED THAT THERE WILL BE WATER OR
SATURATED GROUND CONDITIONS IN THE WORK AREA. THE CONTRACTOR SHALL
CONSTRUCT TEMPORARY ACCESS ROADS THROUGH THE PROJECT AREA AS NEEDED TO
COMPLETE THE WORK. DITCHES, PUMPS, AND SETTLING BASINS MAY BE USED TO
CONTROL EXCESS WATER. THE CONTRACTOR SHALL ENSURE THAT TURBID WATER
DOES NOT SEEP INTO THE BYPASS CHANNEL OR MAIN RIVER DOWNSTREAM.
METHOD OF WORK AREA ISOLATION
FISH SALVAGE OPERATIONS WILL BE CONDUCTED IN THE CROOKED RIVER BY THE GOVERNMENT, WITH ASSISTANCE FROM THE CONTRACTOR, ONCE THE BYPASS CHANNEL IS COMPLETE. THE CONTRACTOR SHALL GRADUALLY BLOCK THE MAIN RIVER, TRANSFERRING FLOW TO THE BYPASS CHANNEL, USING
METHODS APPROVED BY THE GOVERNMENT, TO ASSIST IN DEWATERING THE MAIN CHANNEL AND
MAINTAINING TURBIDITY STANDARDS IN THE BYPASS CHANNEL. THE CONTRACTOR SHALL PROVIDE, AT A MINIMUM, TWO 6 INCH PUMPS TO DRAW WATER DOWN IN THE POOLS. FISH SALVAGE
OPERATION ARE EXPECTED TO TAKE UP TO 5 DAYS.
