Latest Lake Washington sockeye and chinook counts

Here are the most recent Lake Washington sockeye and chinook numbers.

Through Thursday, Aug. 9 the inseason count provided by Mike Mahovlich, a Muckleshoot Tribal biologist, is now up to 145,339 compared to the preseason forecast of 45,871.

The single-day counts are: 1,633 fish on June 12; 687 on June 13; 532 on June 14; 2,183 on June 15; 3,062 on June 16; 1,724 on June 17; 1,515 on June 18; 2,241 on June 19; 6,421 on June 20; 3,548 on June 21; 1,839 on June 22; 1,883 on June 23; 4,100 on June 24; 5,823 on June 25; 1,780 on June 26; 3,730 on June 27; 5,080 on June 28; 2,784 on June 29; 6,529 on June 30; 1,942 on July 1; July 2, 4,539; July 3, 5,765; July 4, 9,600; July 5, 6,133; July 6, 8,491; July 7, 6,098; July 8, 3,978; July 9, 6,335; July 10, 3,582; July 11, 5,362; July 12, 4,630; July 13, 1,602; July 14, 2,535; July 15, 1,211; July 16, 587; July 17, 1,082; July 18, 1,337; July 19, 1,365; July 20, 1,051; July 21, 769; July 22, 1,665; July 23, 967; July 24, 1,421; July 25, 807; July 26, 851; July 27, 617; July 28, 648; July 29, 524; July 30, 523; July 31, 209; Aug. 1 (no actual count but an estimation), 356; Aug. 2, 503; Aug. 3, 398; Aug. 4, 316; Aug. 5, 164; Aug. 6, 65; Aug. 7, 26; Aug. 8, 164; and Aug. 9, 94.

The big urban lake has an escapement goal of 350,000 sockeye before any fisheries are considered.

The last time a fishery occurred was 2006 when a run of 470,000 sockeye returned and allowed an 18-day sport fishery. Other fisheries occurred in 1996, 2000, 2002 and 2004.

This summer’s return appears to be tracking similar to 2010 when at this same time frame 159,695 had returned. The final tally that season was 161,417.

When this summer’s sockeye were in the freshwater environment as juvenile fish they encountered decent water conditions and no major flooding, which probably led to a stronger survival rate. Add to that good ocean conditions when they migrated out.

Since 2006, sockeye returns have dropped close to historic lows, and the run last summer ended up at about 43,000.

Back in 2009, the sockeye fry entered the lake in low numbers so this summer’s adult return wasn’t expected to be that good.

The inseason chinook count at the Ballard Locks in recent days looks like this: July 25, 140; July 26, 52; July 27, 145; July 28, 111; July 29, 207; July 30, 44; July 31, 96; Aug. 1, 165 (no actual count but an estimation); Aug. 2, 235; Aug. 3, 235; Aug. 4, 216; Aug. 5, 154; Aug. 6, 392; Aug. 7, 317; Aug. 8, 337; and Aug. 9, 210 for a total of 3,635. The 16-year average for this point in time is 3,257.

The new permanent hatchery on the Upper Cedar River just below Landsburg Dam can produce more than 34-million fry, but last year it only got 25 percent of that figure from spawned adult sockeye. A run above 100,000 this summer could raise the bar in production number of spawning fish at the new facility.

The new hatchery facility got a 9-million egg take from last year’s sockeye return, and many are hoping to get 20-million from this summer’s return.
