I've spent hours in classes, conducting online research, and asking questions to the Department of Ecology to make this well and water basin post as informative and easy to read as possible. So let's begin.
Not to dive into much back story; the gist is, the Hirst Decision changed the way county building departments decide to approve or deny building permits that use wells as a primary water source. As property owners and potential buyers, if needing to know what watershed serves an address it can be challenging.
This post will aim to answer the following question and deliver information on how to research watersheds and water basins.
- How do I find a watershed for a particular property?
Let's start with the basics.
There are 5 watersheds in Snohomish County and they are the Lower Skagit-Samish WRIA 3, Upper Skagit-Samish WRIA 4, Stillaguamish WRIA 5, Snohomish WRIA 7, and Cedar-Sammamish WRIA 8. Yet, it is very unlikely that a property will need to research the Cedar-Sammamish WRIA 8 since the SW area of Snohomish County relies on city water - view watershed map.
