Water quality data

[Slickcraft]

You can now access the water quality data for Lake Winnipesaukee online at http://winnipesaukeegateway.org/moni...ing-sites-map/

Use scroll wheel to zoom as in Google maps.

Quality is good in open areas but is degrading some in the more confined bays. (that is just my layman's opinion looking at the data).

My wife and I sampled two sites between Governors and Timber the past two years; shallow site GI5 and deep site GIC. Many other volunteers contributed around the lake.

Thanks Slick. Are you just dropping a secchi disc?

No, on the deep site we do a temp profile and take an integrated water sample down to the thermocline typically 8 to 10 meters. We also drop the disk and record the visible depth. This site is in 95' of water so we use a 150' anchor line to stabilize the boat during the 15 min process, can't be very windy.

On the shallow site we just grab a sample at about one half meter.

Then all samples are processed at home, some filtered and filter disks saved. Samples are put into labeled containers which are frozen. The filters and frozen samples make their way to UNH where they are analyzed.
