lake temperature
 

Does anyone know what the lake temperature is?

46° today at the Lakeport Dam.

This is a good resource:

You can click on different locations to get more info (wind, waves, temp, etc).

Enjoy!

I'm getting 46 on my water temp probe installed this week too, which usually tracks the Lakeport numbers closely. The water temp numbers on this site seem to be very different. Time lag? Deeper water?

Warming up fast
 

This data is a bit old, but last Saturday (5/3), I did water quality sampling in the NE quadrant of the lake for UNH. Part of the job is measuring the temperature on the surface and at each half meter down. Across five sites, the temperature at 1/2 meter (or 1.5 feet) ranged from 47 to 52 degrees. Bottom temperatures ranged from 42 to 45 degrees. The thermocline varied from 8 to 11 feet.

Interesting. Why would the NOAA site have such a variance across the whole lake compared to these readings ? Do you know the depth the NOAA is measuring at ?

Even today they have the temps around 43-45 ?

Lakeport has 49 degrees this morning. Should see bass in the flats any time now.

Lake Temperature
 

The water temperature at East Bear Island on Mother's Day was 50 degrees. Saw the Mount cruise by two times on Sunday. Great to see her again!!!

The lakeport Dam is reporting 52 degrees today. Getting there, slow but sure.

Blackcatnh.com temperature info
 

Is the probe down/broken? If so I'd be interested I contributing to help get it fixed as we love having that info for scuba diving! :)

I just read on facebook that there was a death in the family a month ago and that they haven't been there to maintain it. The weather station is slowly coming back on line.

Oh my. Sad news indeed. Thoughts and prayers!

56 yesterday for lake temp at Lakeport. Last year at this time we were 61. Averaging out.

My buddy and I were out and about on Sunday starting around 10am and ending around 6pm. Water temp in the morning started off at 60 degrees and topped out later on in the day at 64. This was picked up off the thru-hull transducer on his Sea Ray Sundeck so it was a good foot or two below the surface. Slowly but surely.

Lake Temperature
 

The water temperature at our place on East Bear Island on Memorial Day was 60 degrees, an increase of 10 degrees from the previous week.

I went for a quick swim this past weekend...brrrrrrr. But the kids on the other hand, the water might as well have been in the 70's as they played in it for much longer then any of the adults could even bear to stand in it...:D

Back on topic
 

Today's temperature gleaned from the Weirs FD rescue boat was 61.7 @ surface. Have a Great day!

It is getting warmer - at the top
 

On Wednesday (June 4), during UNH sponsored water quality sampling, the surface temperatures in the north-east part of the lake ranged from 67 (near Geneva Point) to 69 at States Landing to 70.5 in Greens Basin. The thermocline (where the water gets chilly) ranged from 5 feet in Greens Basin to almost 15 deep near Geneva Point. Bottom temperatures (for you scuba-duba divers) ranged from 54, near Suissevalle to a chilly 45 at the bottom of Greens Basin. By September, the thermocline normally disappears at the sampling locations, which are 25-30 feet deep.

Less frigid water temps combined with the 80's forecast for the weekend should bring out the boat traffic!

61 degrees at a deep site
 

From a 95' deep site between Governors and Timber at 7:30 am today:

61 degrees from surface down to a depth of 15'.

Thermocline at 31' depth.

Depth that a secchi disk can be viewed from the surface - 34'.

http://en.wikipedia.org/wiki/Secchi_disk

Water is very clear today at this deep site, ties the max secchi depth over past 5 years.

Slick;

What kind of temperature variation are you reading at the thermocline? It must be extremely slight...

Dan

We use a change of at least 1 deg C per meter to define the thermocline.

9.5 m was 14.9 deg C (58.8 F) and 10.0 m was 13.5 deg C (56.3 F).

In English units that is a 2.5 deg F change in 1.6 feet, a rather sharp thermocline.

Those temps seem a lot higher then most people are reporting. Also much higher then the NOAA site and other ?

Maybe it was 57, 59 and 60 ?

Temperature graphs
 

The temperatures should be correct. The thermometer came freshly calibrated from UNH just a few months ago. I don't know why NOAA's water temperature data is 9 degrees lower. Perhaps they aren't out in the water doing measurements, but it is strange that they would report if they weren't confident of the data.

Other lake monitors that sampled this week are reporting similar temperatures as what I saw.

The northeast part of the lake gets most of its water from the land (30:1 ration of land to water), is more shallow and is darker, so gets more solar heating. It normally both freezes and thaws well before the broads.

Here is a graph of the temperatures by depth. Greens Basin is different from the others. Excuse the Meter and Celsius format.

Making an August update to show the difference between June and August temperatures and the thermocline. Greens Basin is still the odd one, and in July it was oxygen depletion was measured at the bottom there.

Still odd that so many different temperatures are being reported. I can say that we spent about an hour in and out of the lake Saturday morning installing a dock and the water felt nowhere near 70 degrees !

These last couple of days of sunshine should help it keep going up !

70 degrees at my dock
 

Swam yesterday with the thermometer reading 70 degrees 1 foot down - refreshing :eek:

Water Temperature
 

63 degrees three feet down at East Bear Island last Sunday.

The Lakeport Dam is reporting 67degrees. seems that we are making some good progress. :)

Out on Winnisquam in the middle it was reading 73 degrees yesterday about 2' down, thru-hull transducer on a Sundeck. It was comfortable enough to stay in indefinitely...Summer has arrived! :cool:

I was floating around in the deep water for ten minutes today on a fat noodle....trying to recover from a bearing replacement job on a boat trailer....and that water is a great way to chill out......very cool still for humans ...... probably is hot-tub warm for canada geese.......quack-quack!

65 deg down to about 10' this morning at the 95' deep spot between Gov and Timber. It is a little cooler out there than in the shallow bays.

Thermocline was at about 23', not as deep as 2 weeks ago but the upper layer is several degrees warmer.

there has been no update for lake temps for a long time. Something must be up

My temp probe has always tracked winni temps closely...reading in high,mid-seventies right now...as in about 73.

Yes, the temps are up;)
On Aug 20 it was about 75 deg down to about 30' in a deep spot between Gov and Timber. Then a fairly sharp drop in temp just below that. Will sample again next week; the decline will be starting.
