Seeps in North Beach Park

There is a stream that runs through North Beach Park, emerging from just under 24th Ave NW and running through the park, then through private property to the Sound. But there are also a number of broad horizontal seeps that enter the park. My research will ask a lot of questions about them:

  1. How many are there?
  2. Where do they enter the park?
  3. Where do they enter the stream?
  4. How seasonal are they? (Do they dry up in the summer?)
  5. What is their flow rate?
  6. How do they affect the water quality of the main stream?
  7. What IS the water quality of the main stream?
  8. Do the seeps cause erosion?
  9. How can we stabilize them if so?
  10. What grows on or around them?
  11. How can we remove invasives and plant on them without further destabilization?

There will be some data gathering before I can answer all these questions. The first three questions will be pretty easily answered with a couple walks through the park. Seasonality, obviously, will take at least a year. Flow rate will take several samples to get enough data points for a good average.

Here is a link to the set of pictures for the “Fallen Alder” seep, near, guess what, an alder tree that has fallen across the stream. And here is a link to the set of pictures for the 101 tree seep. These sets will grow as the research progresses.

If you have any ideas for research, please feel free to suggest them in comments.
