In a July 30th post, Grist (an enviro website headquartered in Seattle) presented their photo contest winners on the topic of: "Waste on the Water".Now I ask your opinion, which photo is worse:
b) these photos of Bear Creek near a park area in Redmond.
Well, maybe the Grist photo is still the champ, but these might have qualified for 'honorable mention'! I took these creek photos on July 14, near NE 80th Street & Avondale Way.

Pretty nasty looking, huh?

Your comparison to the Grist article is a perfect match. To what do you attribute the prevalance and location of the duck weed?
ReplyDeleteDuckweed typically grows in places where the water is not flowing rapidly, such as in the eddy seen in the photos, that was created in Bear Creek by the accumulation of various pieces of floating wood.
ReplyDeleteThe website www.environmentalleverage.com states:
" Duckweed blooms typically occur in shallow waters rich in nutrients, especially phosphorus and/or nitrogen. Many studies have indicated that duckweed growth is a function of nutrient levels and not pH and/or temperature. "
Interesting. Do you have any idea what the source of phosphates/nitrogen is in this part of the creek?
