TOWN OF NEW CASTLE
WATER RIGHTS WORKSHEET

(EQUATING FLOW TO EaR'S)

NOTE: THIS CAlCULATION WIll DEFINE THE NUMBER OF EQR'S THAT THE TOWN
CAN SUPPORT WITH THE CASTLE VALLEY WATER RIGHTS TRANSFERRED
AS DEFINED BELOW. (THIS IS A lEGAL AMOUNT OF WATER - NOT PHYSICAL)
BASED UPON THE RESOURCE REPORT (ATTACHMENTS THERETO), THE AMOUNT OF
WATER TO BE TRANSFERRED TO THE TOWN OF NEW CASTLE IS COMPUTED AT A RATE
OF 002 CFS PER 10 UNITS PLACED (OR CONSTRUCTED) ON LINE.
IN CASTlE VALLEY RANCH, 191 UNITS HAVE BEEN PLACED ON LINE WHICH
EQUATES TO-
191/10= 191 x 0,02= 0.382 CFS NEEDING TO BE TRANSFERRED

NEW CASnE SUPPLY IN DRY YEAR= 0 9 CFS
+ 0.382
