Delta Cross Channel Gate Operation

Posted: 5/20/2019

Delta Cross Channel Gates are CLOSED.

Due to high flow on the Sacramento River, the Delta Cross Channel (DCC) gates will remain closed until further notice.

PLEASE NOTE: GATES MAY NEED TO BE CLOSED WITH
SHORT NOTICE IF A FISHERY CONCERN IS IDENTIFIED.

EC and Bromide - Banks Pumping Plant, Jones Pumping Plant, Clifton Court Forebay (EC), San Joaquin River at Vernalis, Gianelli Pumping Plant, Hood (EC)

Again, same as last week; Banks, Jones Vernalis, Gianelli (Delta water) and Hood are reporting very stable and low values due to current conditions; outflow and flushing.

Banks Daily Average: EC - 125 uS/cm, Br - < R.L. (0.05 mg/L), 10 Days ago: 145 uS/cm and < R.L. (0.05 mg/L)

Jones Daily Average: EC - 127 uS/cm, Br - < R.L. (0.05 mg/L), 10 days ago: 113 uS/cm, < R.L. (0.05 mg/L)

Clifton Court Forebay: EC - 140 uS/cm, 10 days ago: 130 uS/cm

Vernalis: EC - 103 uS/cm, Br - <R.L. (0.05 mg/L), 10 days ago: 77 uS/cm and < R.L ( 0.05 mg/L)

Gianelli: EC - 137 uS/cm, Br - <R.L. (0.05 mg/L), 10 days ago: 130 uS/cm and < R.L. (0.05 mg/L)

Hood: EC - 132 uS/cm, 10 days ago: 91 uS/cm

Organic Carbon, TOC and DOC - Banks Pumping Plant, Jones Pumping Plant, San Joaquin River at Vernalis, Gianelli Pumping Plant, Hood

Values have leveled off at all of the stations. It looks like Banks, Jones, Vernalis and Gianelli are all analyzing the same San Joaquin River water. (The graph I use to look at the data shows them all at the same point right now.)

Banks: TOC = 3.2 mg/L, DOC - 2.9 mg/L. 10 days ago: 3.2, 2.8

Jones: TOC = 3.3 mg/L, DOC - 2.9 mg/L. 10 days ago: 3.3, 2.8

Vernalis: TOC = 3.0 mg/L, DOC = 2.7 mg/L. 10 days ago: 3.2, 2.9

Gianelli: TOC = 3.2 mg/L, DOC = 3.0 mg/L. 10 days ago: 3.0, 2.7

Hood: TOC = 1.8 mg/L, DOC = 1.7 mg/L. 10 days ago 1.6, 1.5

Pumping: 6/7 - 6/16

Banks... varied between 6,396 cfs and 6,851 cfs; the 6/16 average was 6,457 cfs.

Jones... varied between 1,613 cfs and 4,377 cfs over the time period. The 6/16 average reported 4,365 cfs.

Gianelli Pumping Plant: Daily average discharge generation (Sal Luis Reservoir into O'Neill Forebay) varied between zero cfs and 950 cfs over the time period. The 6/16 average was zero cfs. Daily average discharge pumping (O'Neill Forebay into San Luis Reservoir) varied between zero cfs and 5,221 cfs over the time period. The 6/16 average was 5,221 cfs.

O'Neill Pumping Plant: Daily average discharge generation (O'Neill Forebay to the DMC) reported zero cfs over the time period. Discharge pumping (DMC to O'Neill Forebay) varied between 880 cfs and 3,226 cfs. The 6/16 average reported 3,169 cfs.

Dos Amigos Pumping Plant: Varied between 5,391 cfs and 7,741 cfs. The 6/16 daily average was 5,391 cfs.

South Bay Pumping Plant: Ranged between 45 cfs and 180 cfs. The 6/16 average was 180 cfs.

Barker Slough Pumping Plant: Varied between 74 cfs and 110 cfs. The 6/16 average was 110 cfs.
