Keep Green Lake ‘Weir’d

September 25, 2015 7:59am


Okay, so a confession. I hadn’t heard of a “weir” until I received a few emails notifying us that they were going to be repaired. (I’ll save you a trip to Webster’s and tell you the definition: A weir /ˈwɪər/ is a barrier across a river designed to alter its flow characteristics. – Okay, good to know.)

So what about these weirs?

Remember our post a few weeks ago about the low water levels at Green Lake? Well on the opposite side of that coin there is a system that helps prevent Green Lake from flooding. Near Meridian Ave. N and Sunnyside there are outflows that help water leave Green Lake and into the stormwater system. Seattle Parks and Recreation and Seattle Public Utilities is updating this system, which is called the outfall vault, and will be installing an internal weir (ah, there it is!) gate to help regulate the lake’s level.

Work begins Monday September 28 and is anticipated to be completed by Friday October 28. Expect intermittent trail diversions during the work to allow equipment to access the area.

Friends of Green Lake will also be posting more about this project, so be sure to check on their site for more info.
