UPDATE  Sep 4, 2023: There is still – a month and more after the Big Precipitation Events –  a lot of water being held back by the intact landscape. See below

Sandy Lake fan and top Sandy Lake iNaturalist reporter Sybil Nunn recently spotted the red-topped post at right in the water at Sandy Lake, just below the big parking lot.

She wondered what it’s for and speculated it’s for monitoring water levels.  That seems logical as there was massive flooding of the lake and many low areas withon in the Sandy Lake watershed in late July and early August and further downstream in Bedford. Two residents close to Sandy Lake estimated that the lake rose 5-6 ft above previous levels, and said it only started to come down a couple of weeks back. Continue reading →

Sandy Lake (Bedford, NS) limnological profiles reveal freshening and oxygenation of the water column after extreme rain events; and a worrisome “Metalimnion Oxygen Minimum” 2Sep2023

After  extreme precipitation events earlier in the summer of 2023, the entire  water column had lower conductivity values ( a measure of salt content) on Aug 14 compared to May 22  and bottom waters on Aug 14 were better oxygenated than on 6 other occasions in the past when deep water oxygen levels were measured in late summer/early fall. This flushing and oxygenation could be good news if there weren’t other adverse effects of the heavy precipitation. Observations in the latter half of August in 2021, 2022 and 2023 show the presence of a “Metalimnion Oxygen Minimum” at 5-6 m; it appears that it reformed quickly after the high precipitation events in 2023.  The occurrence of a Metalimnion Oxygen Minimum in Sandy Lake represents significant deterioration in water quality of the upper layers of the water column and  adds yet more reason to be concerned about the state of the lake currently and the possible impacts on lake water quality if the proposed major development on its headwaters was to proceed.

Posted on August 12, 2023 by admin

UPDATE Aug 16, 2023:
Forest ecologist, Donna Crossland, explains the significance of the discovery of Hemlock Wooly Adelgid – or HWA – in Bedford, NS (Audio)
CBC Maritime Noon

Subject: HWA Working Group – HWA Detection in Nova Scotia
Date: Fri, 11 Aug 2023
From: Neville, Ron (CFIA/ACIA)
Hi there,

We wanted to pass along the following HWA update from Sherry Lynn Kelly, the CFIA Director of Operations for Nova Scotia.
***************************
Good Afternoon,

In early August, the CFIA received a report of a suspected Hemlock Woolly Adelgid (HWA) infestation on a home owner’s property in Bedford, Nova Scotia. The resulting laboratory analysis of samples taken by CFIA during follow-up has confirmed the presences HWA. The is the first confirmed detection of HWA in the Halifax Regional Municipality. The affected property has been placed under regulatory control and additional surveys in the surrounding area will take place in the coming weeks to better characterize the population.

“Here’s what Halifax wants you to know about blue green algae” 28Jul2023

Posted on July 29, 2023 by admin

That’s the title of an article in the Halifax Examiner by Zane Woodford, July 28, 2023.

The article describes what to look out for, how to distinguish BGA (Blue-green algae) from pollen or even an oil spill. “The difference is that the blue green algae is under water too, whereas pollen and oil sit on the surface.” It’s a very informative article, telling us, for example, the differences between algal blooms and benthic mats of BGA that can coat the bottom – it’s the latter that have been associated with death of dogs.

Regarding Case 23307 – Bedford West subareas 12 & 1 Special Planning Area 25Jul2023

Initial Comments  in reference to the request for public feedback on Case 23307 – Bedford West subareas 12 & 1 Special Planning Area. I have spent some time in this area as a retired Biology Prof/naturalist looking at the landscape and wetlands, and making some measurements of salt content of the surface waters in relation to a broader assessment of the state of Sandy Lake and Environs begun in 2017 and ongoing as reported at www.versicolor.ca/sandylakebedford. My observations are made in support of the broad objectives of the Sandy Lake-Sackville River Regional Park Coalition, and of the Sandy Lake Conservation Association but are conducted and reported entirely independently of those organizations.
– David Patriquin

I  submitted these comments to Dalih Salih, Senior Planner, HRM, cc to Kevin Neatt  (V.P., Clayton Developments), NW Community Council, Sandy Lake Conservation Association, Sackville Rivers Association. View
Covering Letter

For Brevity, I refer to Bedford West subareas 12 & 1 as  “BW12&1”

Some important features of  BW12&1 and just downstream:  Continue reading →

Update ug 2, 2023: E. coli results from the Beach Monitoring program at Sandy Lake indicate very low levels of E . coli at 5 locations across Sandy Lake Beach, ranging from ‘Non-detect to 4.0 CFU/100ml. Samples were taken on Monday, July 31st at just before 12noon…As a result, Sandy Lake Beach has been re-opened to swimming.
Update 17Jul2023: HRM Public Service Announcement
“The Halifax Regional Municipality is advising residents that Sandy Lake Beach in Bedford has reopened to swimming.
Sandy Lake Beach is a supervised beach. Municipal staff regularly test the water quality at all supervised municipal beaches, as well as two unsupervised beaches, during the summer months.
Previous test results showed high bacteria levels in the water, but follow-up tests now show the water is once again safe, in accordance with Health Canada guidelines.”
