On a few-degrees-below-zero day in early February, I set out from Sandy Lake Beach Park to go to Marsh Lake. I especially wanted to see the hemlock-lined Upper Peverill’s Brook in winter, where it flows into Marsh Lake.
Sandy Lake was frozen sufficiently that I could walk on it – but I stayed over shallow water just in case. I headed north and took a right turn at the point I figured was closest to Marsh Lake. I headed up the drumlin; the ground was frozen with a few inches of snow on top, perfect for walking (I had cleats on) and for walking with minimal impact on the environment. Such days are my favourites for hiking into areas when you have to cross water and wetlands and the like to get to them. Continue reading
On a lengthy winter outing in the area of Sandy Lake on a slightly above zero day this past week I noted several sites where sediment is flowing into streams that flow into Sandy Lake or Marsh Lake, or that lie directly on Sandy Lake.
Puddling on Jackie’s Brook
The first site was on a power line where a significant stream flows out of the forest on one side and into the forest on the other and there is extensive puddling from OHVs crossing the stream. I think the stream is known informally as “Jackie’s Brook”. It goes into the woods, falls down over the edge of ridged bedrock outcrop and then crosses the powerline again on its route to Marsh Lake; there is also extensive puddling at that second crossing of a powerline.
OHV (Off-Highway Vehicles) use on publicly accessed lands can be very controversial, and is banned in HRM Parks unless specifically permitted (By-law P-600). Personally, I am OK with OHVs accessing power lines but…not without significant responsibilities and accountability. One solution: OHV organizations take responsibility for managing ATV routes in such areas, e.g. see this document describing how OHV use was/is managed in the Five Bridge Lakes Wilderness Area; their involvement this way was a big factor in gaining community and political support for establishment of the Five Bridge Lakes Protected Wilderness Area in 2011.
Just in case anyone is looking at these pages… I am reorganizing and revising them.
I expect it will be completed circa mid-February, 2o21

Sandy Lake is a near-pristine lake lying within a partially developed landscape in the suburbs of Halifax, Nova Scotia. The Bedford Lions Club led the way for establishing the Sandy Lake Beach Park in 2003/4.
It’s a wonderful spot, for children especially, with safe swimming, paddling, fishing and opportunities for diverse nature activities. Mixed Acadian forest with patches of Old Growth occurs on drumlins by the Beach and is readily accessed via old forestry roads.
There is pressure to develop in an area of the watershed that provides most of the water for the lake.
In this presentation to the Bedford Lions Club on Dec 3, 2020, David Patriquin describes
– the benefits of the lake and the surrounding area for recreation and wildlife (0-19 min);
– some interesting features of old growth forest on the drumlin by the beach (19-32 min);
– life in the lake and possible impacts of further development in the watershed on lake water quality (32- 67 min).

Help us expand the existing park to protect this irreplaceable natural area. Time is running out.

An article in HalifaxToday tells us “Flooding in Halifax [peninsula] shouldn’t be a surprise” as historical maps of the city show it was built over dozens of wetlands, bogs and streams… View
Flooding in Halifax shouldn’t be a surprise, says archaeologist, by Chris Stoodley in Halifax Today Oct 10, 2020
After Halifax saw heavy rainfall earlier this week, an archaeologist says people shouldn’t be surprised about flooding.
On Oct. 5, flooding trapped at least one car on the south end of Barrington Street in downtown Halifax.
Jonathan Fowler, a Saint Mary’s University archaeologist, says it’s bound to happen as historical maps of Halifax show numerous brooks, streams, bogs and wetlands running throughout the peninsula.
Sandy Lake, but not Marsh Lake and Jack Lake receives waters from storm sewers
At a special meeting of Halifax Regional Council on Sep 22, 2020, councillors passed Item No 11.1.4 Grade Alteration By law and Halifax Stormwater Standards for Development Activities.
Said Sackville Rivers Association President Walter Regan in a letter to Mayor and Councillors:
Please vote and pass Item No 11.1.4 Grade Alteration By law and Halifax Stormwater Standards for Development Activities
This new by law will help all of HRM and the environment by keeping the silt out of our local water courses ( including the Sackville River) and water in the ground where it’s needed for ground water recharge and the slow release of clean, cool and clear water to our rivers and lakes.
It will help reduce the capital and maintenance costs of infrastructure.
If done correctly can add to the beautification of local areas, protect wetlands and save our lakes and rivers from pollution and negative impacts from construction and storm water runoff while maintaining natural water cycles.
Will help reduce the negative impacts of Climate Change and local flooding (especially in areas like Bedford and Sackville). Continue reading
Pit and Mound topography in hemlock/yellow birch forest by Sandy Lake. Based on the ages of the oldest trees, I speculate that they were formed following a massive windfall during the Saxby Gale (1869) or the Great Storm (1873).

Hurricane Teddy is tracking northward and “is expected to impact Atlantic Canada and the Gulf of St. Lawrence region Tuesday and Wednesday as a “very dangerous” post-tropical storm as it moves through the region, bringing strong winds, heavy rain, storm surge and pounding waves” (CBC Sep 19, 2020
They might have added tree falls (tipovers, windthrows) to that list.
My spouse looks out the window at our urban forest and at a towering tree on a street one block to the north; she worries that it may fall to the southwest and on our house and asked me what I thought. “I don’t think we have to worry, at least this time around” I said. “Why”, she asked. I said “Because I looked at the tree, it is about 3.5 ft diameter and looks very healthy; it has already survived Juan and Dorian and right now it looks as though this storm will not be worse than Dorian and nowhere near Juan in ferocity; and finally, even if the winds blow it over, it is likely to fall towards the west or north and not towards us.
“Why do you think so?” she asked. “I have been thinking about windblown NS forests” I said. Read more on Nova Scotia Forest Notes
