Aquaculture & Ditches
The diverse aquaculture system at 21 Acres demonstrates the relationship of aquatic farming practices to natural features such as streams, ponds, and marshlands. In addition to carefully selected harvestable crops, native plants are strategically integrated into the landscape as complementary features to the ecosystem as it continues downstream.
These ditches flow into the Sammamish River (or Slough as it’s sometimes known). You’ll see different maintenance plans along the ditches throughout the Farm. Water has not flowed through here for many years. Several different approaches are being used for ditch maintenance; a major area of interest for King County’s department of Natural Resources. You’ll see some of the areas planted with jute for weed control, some with native plants and harvestable crops and some left natural.
Water actually flows through the ditches now (perhaps not during some of the hottest weeks of the summer) and we’ve viewed a variety of wildlife enjoying the stream.
