Ballard Locks Salmon Migration 2024 Documenting Record-Breaking Fish Ladder Activity in Seattle's Urban Waterway - New 2024 Seal Deterrent Program Successfully Reduces Predation at Lock Entry Points
A new program implemented in 2024 at the Ballard Locks aims to reduce the number of salmon consumed by harbor seals during their crucial migration through the lock's entry points. This new approach uses underwater pyrotechnic devices, also called "seal crackers," to discourage the seals from hunting in these areas. The program replaces an earlier method known as Targeted Acoustic Startle Technology (TAST), which, while successful in pushing seals away from the fish ladder, was eventually discontinued due to conflicts with other management protocols. Though early results are encouraging, suggesting a decrease in seal predation on migrating salmon, the program’s effectiveness is still being closely observed. This program is a testament to the challenges of balancing urban development with the ecological needs of wild species. The success of this new seal deterrent program, coupled with record-breaking fish ladder usage, could potentially enhance the already impressive salmon passage numbers observed this year. However, the continuous monitoring and adaptation of management practices will remain crucial in maintaining a delicate balance between the salmon population and the seals that inhabit the region, ultimately fostering a healthy ecosystem within the Seattle urban waterway.
A new seal deterrent program, initiated in 2024 at the Ballard Locks, utilizes underwater acoustic devices to discourage harbor seals from preying on migrating salmon. The program's aim is to lessen predation at key lock entry points where salmon are funneling through during their migration. This approach builds on earlier trials using Targeted Acoustic Startle Technology (TAST) between 2020 and 2022, which effectively kept seals at a distance from the fish ladder, even with the seal population remaining stable in the area. However, the TAST program was ended in the summer of 2022 due to its incompatibility with other management strategies at the locks.
It's worth noting that the potential impact of harbor seal predation on salmon is substantial. Estimates from the Washington Department of Fish and Wildlife suggest that harbor seals consumed a staggering 52 to 26 million juvenile Chinook salmon (smolts) in the Puget Sound annually, a figure highlighted in a 2016 study. The new acoustic system, deployed on the west side of the Ballard Locks, seeks to create a sound barrier that discourages seals without harming the seals or salmon.
Early observations suggest this new device might be effective in reducing predation, offering hope for improved salmon survival rates at this critical point in their journey. The Ballard Locks is a significant bottleneck for salmon migrating, where seal predation poses a major risk to the salmon. These seal deterrent efforts are part of a wider project that involves various organizations dedicated to bolstering salmon population health. It's interesting to observe that the recent record-breaking fish ladder activity has coincided with the implementation of these seal deterrents, suggesting a potential positive correlation. However, it's still too early to definitively claim that the increase in fish passage is a direct result of the seal deterrents alone, as other factors could be at play.
The success of the seal deterrent program is still under evaluation and is a compelling example of how human engineering can be used in a potentially beneficial way to reduce human-wildlife conflicts in urban areas. This approach also highlights the continued challenge of finding solutions for complex ecological problems that can impact the success of our urban water management efforts. Future study of this novel approach to seal deterrent technology will be interesting and hopefully contribute to improved salmon conservation and urban ecology research.

The city of Seattle has implemented various projects to improve salmon habitat within the watershed. Restoration projects such as the construction of a fish ladder in the Cedar River are intended to encourage salmon returns after a century-long absence. The success of these efforts likely plays a role in the observed spawning numbers.
There is a complex interplay between genetic diversity, habitat, and salmon survival. The October spawning numbers, with their higher than normal genetic diversity, suggest that these populations are relatively healthy. This observation is vital, as diversity enhances a species' long-term resilience. It appears smaller tributaries within the watershed are gaining importance as key spawning areas.
Intriguingly, the recent smolt-to-adult survival rates may have seen an increase of up to 20% this year. It remains unclear whether this is a direct outcome of improved watershed health or related to factors like food availability or insect population control.
The record-high spawning numbers observed at the Cedar River are happening simultaneously with high fish ladder activity at the Ballard Locks. The interplay between these two locations highlights the need for long-term ecological monitoring to comprehensively understand the implications of the changes. Continued monitoring and research are crucial to decipher whether these current changes are a short-term fluctuation or a sign of a more substantial and long-term change in salmon behavior and population dynamics. The Cedar River's example suggests that even in highly urbanized areas, salmon populations can adapt and potentially thrive if suitable conditions are created. This observation has implications for how we design and manage urban environments moving forward.
