I followed the link, and it does look interesting.
=20
I predict that eutrophication will be a growing problem here, as well, =
if summers get hotter and drier and predicted (Dare we say =E2=80=A6 as =
being experienced?=E2=80=9D) Our studies down here in God=E2=80=99s =
country over the years have been showing a positive relation between =
rainfall and water colour (which can be translated as dissolved humic =
material). When rainfall is low, colour levels drop, and lakes appear =
susceptible to blooms at lower levels of nutrient. Kinda makes sense: =
light penetration is greater when colour is lower and some of those =
organic molecules may react with nutrients.
=20
We suspect phosphorus of being a greater problem that nitrogen in our =
lakes, but the idea is still interesting.
=20
In the meantime, lake and river front property owners can help by =
leaving their shorelines the blazes alone. Wild shorelines do a great =
job of absorbing nutrients and runoff, thereby controlling turbidity, as =
well. Folks, those nice lawns going all the way down to the lake are =
a terrible idea, especially if you fertilize them! =20
=20
Something else to worry about: The science of cyanotoxicology is =
evolving, but they keep discovering a growing number of very nasty =
toxins in blue-green algae. The effects they have on us humans varies, =
but the mix includes carcinogens and some neurotoxins, for a start.
=20
Public education helps, and so do municipal by-laws. But a lot more =
education is needed, and we need PROVINCIAL regulations to control the =
fun and games still being played on lake shores. Regulations with =
consequences for both contractors and property owners.
=20
I could write a lot more but for God=E2=80=99s sake, keep lake shores =
wild!
