THE DISTRICT CONTINUES TO tARRY OUT A PLANNED, CONTROL PROGRAM FOR ALL ANNUAL,

BROAO-LEA~ WEEDS AS WELL AS PERENNIAL NOXIOUS WEEDS.

Du~ TO THE EXCESSIVE AMOUNT or

RAINFALL FROM MID-ApRIL THROUGH JUNE, THE WEED CONTROL PROGRAM CONSISTED or ONLY ONE

APPLICATION OF CHEMICAL FOR CONTROL OF THe BROAD-LEAF ANNUALS.

ALTHOUGH IT APPEARED

ADVANTAGEOUS TO RE-SPRAY IN CERTAIN AREAS, THE WARM TEMPERATURES AND LACK Ot MOISTURE

PREVALENT IN LATE JULY, ALONG WITH THE LUSH GROWTH OF GRASS, MADE IT NECESSARY THAT WE

LIMIT OUR WEED CONTROL PROGRAM FOR THE BALANCE OF THE SEASON TO MECHANJCAL CUTTING.

As PREVIOUSLY REPORTED, THE USE OF TQRDON FOR AL~ NOXIOUS WEED CONTROL CONTINUES

WHEREVER REQUIRED.

CONTROL OF CANADIAN THISTLE WITHIN THC CANAL RIGHT-Or-WAY HAS BEEN

VERY SUCCESSrUL SINCE THE FIRST USE Ot TOROON WAS MADE IN THE IRRIGATION SEASON or 1965.

IN ADDITION TO ITS USE ON CANADIAN THISTLE, IT is ALSO Bf.ING UStD ON MULLEN, SINCE THE

USE or OTHER CHEMrCA~S HAS NOT BEEN TOO SuCCESSFUL ON THIS PARTICULAR BI-ANNUAL.

~

DISTRICT PERSONNEL CONTINUE WITH THE NEVER-ENDING TASK OF REPLACING WARNING SIGNS

AND ADDITIONAL SAFETY FACILITIES IN THOSE AREAS MOST FREQUENTED BY THE PUBLIC.

THE USE

.

OF CANAL RIGHT-OF-WAY ey UNAUTHORIZED PEOPLE APPEARS TO aE ONE OPERATIONAL PROBLEM THAT

WILL aE CONTINUOUS ~ND WILL REQUIRE ADDITIONAL EFFORTS TO EDUCATE THE GENERAL PUellC AS

TO THE HAZARDS INVOLVED.

PRIOR TO THE 1967 IRRIGATION SEASON, A SECTION OF CONCRETE LiNING REQUIRED REPLACEMENT

ON HANSEN SUPPLY CANAL. THIS PARTICULAR PIECE OF LINING HAD BEEN SUSJrCTED TO EXCESSIVE

SUe-GRADE MOVEMENT, tREEZING, AND THAWING AND HAD DETERIORATED TO THE POINT WMERt IT

REQUIRED REPLACEMENT.

REPAIR PLANS WERE PREPARED ~OR THE AREA INVOLVED AND QUALIFIED

CONTRACTORS WERE ASKED TO SUBMIT BIOS ON THE WORK.

A TOTAl SUR~ACE AR~A o~ 3.100 SQUARE

FEET OF CONCRETE, CANAL LINING WAS REPLACED FOR A TOTAL, CONTRACTED COST OF $3.\30.40.

THIS AMOUNTS TO A LITTLE OVER $t.OO ~ER SQUARE rOOT AND INCLUDES REMOVAL OF OLD CONCRETE;

,

ADDITIONAL EXCAVATION AND FINE GRADING AS REQUIRED; PlACE~ENT AND FINISHING OF ALL NE~

CO~CRETE MATERIALS.
