VOL.37 • ISS. 02 FRESHWATER Jan 18 - Feb 2, 2018 Delta Smelt Numbers Reach New Low as Reclamation Aims to Increase Pumping I n spite of a record water year in North- ern California, the abundance of Delta smelt recorded in the state’s annual fall midwater survey (FMWT) is the lowest in the survey’s 50-year history. The results of the survey were an- nounced as the Trump administration aims to increase pumping and take other mea- sures to “maximize water deliveries” for Central Valley Project irrigators, making conditions even worse for the smelt. Only two Delta smelt were collected at Delta index stations in October. One was from Suisun Bay and the other from the confluence of Sacramento and San Joaquin Rivers, reported James White, California Department of Fish and Wildlife environ- mental scientist, in a memo. The CDFW collected no Delta smelt in September, November, or December. The health of the fish populations is measured by means of the CDFW’s “abundance index,” a relative measure of abundance. The Delta smelt index dropped from 8 in 2016 to 2 in 2017. The agency collected the smelt, along with other five other pelagic (open water) species, in trawl nets at 100 index stations throughout the Sacramento-San Joaquin River Delta, the largest estuary on the West Coast of the Americas, from September 1 through December 13. “The population is so low that they can’t find each other to mate,” Tom Can- non, a fish ecologist and consultant for the California Sportfishing Protection Alliance, told Alex Breitler o bFR7F6F&V6&B( v^( &RV6FfR6VBGW&rFR7B&rvFW"V"#FPV&W"bFVF6VB7&V6VBFVFW2'WBBF2V"ƖvVB'w&'W6W72w&W2@6VfW&WV&Ɩ66w&W72Ц2( 6֖~( 7W6VFǐ7FFrFRvbFVƗfW&W2bFVFvFW"F'&vF'2FRFVF6VB2f7BF6F"7V6W2FBFV7G&FW0FRVFbFRFVFV677FVƖRFP&fW&&( 6'FR6֖R( ХF&VRFW"7V6W27W'fWVB'FPvV7vf6VB7G&VB&72@W&66BFB&VFfVǒ&WGFW"FRvvFW"fr6FF2FBBFPFVFg&FRfF&Vv7VW"GvFW'2F&VFf6BB67&VF7ƗGFFF( Bf&R6vVFR'VF6RFWf"vf6VB6W6bFRFVF6VB&6Rg&r7@V"FC#rFRvW7B66R#26WfVGvf6VBvW&R6V7FVB@FW7FF2FRFWf"7G&VB&72V vVf6&6Rg&#BFCsFRvW7@66R#F&VRVG&VBWGRvRУ7G&VB&72vW&R6V7FVBFRV&W"f"W&66BFW V"vVf6&V&VFVBg&32F2bFRvW7B66R#2GvFW6@F&VRVG&VBfgG6WfVW&66@vW&R6V7FVBFRF&VFf6BFF( BF2vV0G26W6FRW&66BFRF&VFfখFWFV6ƖVBg&ccF#FR6WfVFvW7B7W'fW7F'ǒ#c"F&VFf6BvW&R6V7FVBFRV&W"f"67&VF7ƗGFFfRV&W"bFR֖rf֖ǒ( 6w26FVrG&VBbfW'ƗGFRF6F6b7ƗGFduB( 6BvFRǒR7ƗGFv26V7FVBBখFW7FFFV6V&W"g&7V7V&FW"7ƗGFvW&R6V7FVB6WFVЦ&W"7F&W""fV&W"g&FW ֖FW7FF26BvFRFfWrFRF&RbFǒ'VF6PF6W2vW&SGGwwrFfr6vbFVЧFFFfwBF6W27PW2bvVֶv6v0&R斶R6W2BFWF0&V62( ħW7BFN( vR&7FW Bv&R7FFW2FB&VGW FvV2&R( FRV6W"6W"WW.( FR&VW'2FG2( FB2f&WfW.( ЦB$rVWVf6ǒ62F&P( FRVFFRG&fr6^( खFR&Frv&BvƖR&G22আ2G2v6F66v6fFVFǐ6֖rF&R( 6ǒFR&W7N( vƖP&G2267W7FV֖VЦ&BVf7GW&W"6FVB6WFW&&Vvv6RfVFW"vƖRƖrЧv'F&Vv'VFrG&gB&G2WB`2v&vRFRFR( c266RFVvƖR&G227&VFVBWr7FF&@bVƗGFRvFWvFW"GW7G'F&VvFV"&GV7BƖRbvVFV@V֖VG&gBBvW"&G2आvWfW"ƗGFR&W6V&6&WfV2F@( 6ǒFR&W7N( 2&RFW7B6F66vFW6RvW&gVv&G2&P'F&6W 'WF7vr7V66W72WF26R&rFffW&V6RFFRFFVF"FPFW( 6BR( FRFBFVF6VB&R7F'VF@VVv6W26FBf7W6VB6Ɩp6fBFVf"WRFV6VVrB&&V6V7Fr6VBRFf"26VB7VGW&R&Цw&( RFVB( vB2FW&W7Fr2FBFRF6W0f"7G&VB&72BW&66B6pf&ǒ7G&r6FfR&W76RFFRvW@vFW"( R7FFVB( &FfRFbЦ&W2'fRWfVW2FB&RW7GV&RFRЧVFVB6'&VBFW&R'vW"fw2FW&R&WGFW"F7F'2bgV7FpW7GV'F&R6VBFW6RF2FPFBF6W2f"7ƗGFBF&VFf6@&RVvW72&V6W6RFReuB2BvBv6RFV( ФV&W"bf7F'2fR&W7VFVBFPFV6ƖRbFVF6VBBFRFW"Vv07V6W26VFr7&V6W2F72@f6fR7V6W2'WBf7F"2VV@&V6FFRFR66RbFVFf67RЦ6W2&RFFRW'Bb&rVFFW0bvFW"Fw&'W6W72B6WFW&6Ɩf&vFW"vV6W2g&FR7FFPBfVFW&Vrf6ƗFW2FR6WFFVFfW"FR7BSV'2FR&V6&BFFf"vFW"W'G26VFrvFW"FfW'FVB'FR6G&G"WFW"S( V77vW.( 67F6B'F&VVGV7Bv6VB6V@v2bc327&RfVWB#FBv0VWFVBvWBV c27&RfVWB&RFFR&WfW0FW&R( Ɨ2V77vW.( vFR6V@&V6&BbbCs7&RfVWB6WB#RFV6ƖVBWfV&V6&BvFW"V"vV66&FrFEu"FF&v7G2vVBfRWV7FVB&V&VBFRFVF6VBW7W2G&7Ц66&FrFG"WFW""RF7FЦ6f7W22VFvW&VB6VB&WB"wV6VB&fW76"VW&GW2BFRFW'BЧF"6W2rFR6W&FRf֖ǒVBbvFƖfRf6B66W'fF6RFR7B'VFBf6fVBFP&w6VFW"f"vFW'6VB66V6W2W7GV'FBV&W&VBFR֖Ɩ2FPT2Ff2f62FV6ƖVBG&F6ǒ&V6V@( FR7vW"2FBvR&VǒF( @V'2শrFR&W7BWF6F`fVBǒFR67&VF6Ц2FBV&W'2&R6rFB7&V6PV&fW"FVFFR6VBǒ&G0"FV7&V6RFRFWvVBB&PFRg&W6vFW"6GvFW"֗rR`FWFV7F&RvFFRdB6Ɩr( R6BFRW7GV'W6WBGW&rG27vp( FW"2FBFW&Rv26V6vFW 6V6FN( 2vVB֖w&FW2W7G&VЦ7BvFW"FB6VBvW&R&RF7W'6V@Fg&W6vFW"fvrvFW"( f'7BfW6( ЧFW7VBB&BFRfFpfrWfVG2&VB&6FFW3F2vVBVWV&W'2rvVFR6VB2fW'7W66WF&RFV&W'2&R2r2FW6V&ǒ&Rf 6vW2FRVf&VF6FF06VB&Ff7F'26ƖrF7G&ЦbG2&FBGVRFG2RזV"ƖfV76PCSfbvƖRG&gB&G27GVǒ&6VB'6&GV6pf"&fW76f6rwVFW2vFWvFW VFW67G2B&V7&VF&FW'2vFv7FF&G2v67BvƖR&B0FRVFFR7W7F'VBV֖V&BVƗGb7&gG66Rǒ2F6VRFR7GW&RW&fV7@
