Ryan The agreement for release of water f'r-o«; Matilija Reservoir this SU~l1er called for a release of about 240 acre feet in July. ~1ater was released for six dayst beginning July 5tt and ending July 11th. The rate of release varied from 18 crs to 30 crs and averaged 23+ crs. The amount released~s as fo1lows:­ Inflow to reservoir 23 ac. ft.

The 138 acre feet passing ~eyer Road, on the surface, during the six day perdod all sank within the first two miles below I'leyer rtoad. None of it reached Baldwin Road on the surface. The amount of water stored in the reservoir at the end of the rp.lease period was 314 acre·feet. An effort will be made to hold this amount until September 1st and nUease only that which flows into the reservoir. RHJ/g1 I -~-1# COUNTY OF VENTURA STATE OF CALIFORNIA OFFICE OF COUNTY SURVEYOR COURTHOUSE. iOOM 4 VENTURA. CALIFORNIA March 7, 1950 Honorable Board of Supervisors Ventura County Flood Control District Ventura, California Gentlemen: Herewith is submitted a report as of March 7, 1950 on the opera­ tion of Matilija Reservoir. In the absence of instructions to theoontrary this office does not intend to store any ,water in I~tilija Dam which is not surplus and belonging to the Flood Control District.- The reason for this is that upon the release of water from the reservoir, it is assumed'to become free water and upper water right users usually take the major portion of the released water although theoretically the water belongs to all of the users down stream. This office intends to release water that is not considered surplus and will do this as long as the river sands are receiving this· water by percolation and none of it will pass Bster Park. At present there is no flow of water past Burnham Road or Santa "'na Boulevard.. It is our intention to let out 5 or 6 second feet of the ,flow and arrive at a release which will satisfy the purpose of perco­ lation and yet not waste. This matter is offered as an explanation fr~m this office and for discussion as the Board sees fit. ROBERT L. RYAN Engineer Ventura County RLR/s Flood Control District encl.
