Lac Seul flow?
Does Lac Seul flow from east to (north)west? Does the **** at Ear Falls hold back the water in the lake--control water level? I always like to know if I'm going down stream or up stream!
Where Lac Seul connects with the English River on the far east end, is the river flowing into Lac Seul? Pelican Lake flows INTO Lac Seul? Is Lac Seul technically a reservoir? Like our big Army Corps of Engineer projects in the US? In Minnesota we have the Laurentian Divide where the water either flows to Hudson Bay, to Lake Superior or to the Mississippi. I did look this up on Wikipedia and got no help. |

Lac Seul is a reservoir. I don't know exactly what the head on the dam is, but I believe it is a relatively low dam that slightly raised the level of an original lake, so it isn't like most USACE projects.
It does flow out at Ear Falls into the English River. The English River merges with the Winnipeg River (after it leaves Lake of the Woods) which flows through Lake Winnipeg into Hudson Bay via the Nelson River. Lake of the Woods is fed by the Rainy River and other smaller watersheds. This map shows the direction of water flow: The Atlas of Canada - Toporama This map doesn't have water flow, but loads much faster: https://mappingsupport.com/p/gmap4.p...1097&z=13&t=t5 Last edited by jsmyers; 08-12-2016 at 11:00 AM. Reason: added link; corrections and additional information about the watersheds |

The dam that makes LS is at Ear Falls and you drive over it on the main highway. Not a large dam, but appears deep. Interesting.
I've never detected much if any current while fishing LS. Maybe there is in some of the necked down areas, but out on the lake? Not so much. There are a lot of smaller streams flowing into LS, but I think the largest source is the English river. I don't know where the main channel used to be prior to the building of the dam at Ear Falls. I'm sure there are folks here on WC that could answer that question. I've had guys tell me that the travel routes marked on some maps are the old channel, but I don't know that to always be the case. Where those travel routes take you does not always make sense to me. Interesting link in the above post showing flow patterns on the lake. I wonder who figured that out or is it just extrapolated data? I'm hoping others chime in as this is interesting. Pooch

Lac Seul water level
If you look at the link here, http://lwcb.ca/waterflowdata.html, you will see that the entire outflow of Lake St. Joseph is diverted south to the Rat River in order to maintain the pool level of the Lac Seul reservoir. The water level of Lac Seul is measured in 3 places. Hudson on the east end, Lac Seul Post in the center on the north side and finally at Goldpines about 4 miles upstream from the dam at Ear Falls. When the dam was built in 1928, the water level rose about 18 feet. If you look at the graph, you see that the water on the east end is higher than the west end because it is virtually impossible to raise the water level on a lake that is 150 miles long all at the same time. The water will always be higher where the streams enter the lake. It takes time for the water to disperse. As you motor out on the lake, the red buoys will be on your right as you travel upstream. I wish you well, there are very few years where I didn't have to replaced a prop when fishing Lac Seul.

The dam at Ear Falls, Ontario is a working hydroelectric power source and it is holding back way more that 18 feet of Lac Seul's water. It has to be at least a 30 to 40 foot drop as you look down while driving over the daam's rode going to Ear Falls. I was there in July 2016. It has fulltime crew of at least 10-15 guys maybe more by the number of all the pick-up truck parked around the site and at their administrative headquarters down the street. I saw 4- 5 guys alone working on the cranes.

From the SE area, the English River travels north to meet up with the rivers coming down from the NE as mentioned above. Every map I have looked at says the current line changes on the south side of Taylor Island. With the posted information, it now looks like the current change may actually be further north by Bear Narrows and then start a WSW journey towards Ear Falls where it eventually exits through the dam. On the SE section,if anyone has fished or boated through Crooked Rapids and Manitou Rapids, you will see and feel the power of the current. Taking a HB though these areas can be pretty interesting to say the least. Pooch, as far as the original channels and navigational routes, my experience is only with the SE and NE sections. I would have to say that most of the nav routes used today would be very close to original channels and current flow on the watershed. I think at one point in the past,you mentioned that you may have the same wall map that I do of Lac Seul made by Navionics. Without having studied the current flow link closely yet, it appears that the main nav routes on that map follow the current flow in the link for the most part. This leads me to believe the nav routes are closely related to original channels. Having said that, channels shift constantly during high water years where current rates can be quite a bit stronger. I agree that this is a really interesting link to pour over this fall and winter. I think there are thousands of new fishing spots to try based on the current flow. PjShorthorn. |

To be clear, I don't believe that the GIS data says anything about the current flow within a large lake, but rather is a network model of inflows and outflows. Once the water reaches an open expanse, its flow is dictated by too many factors to be predictable.

Click on the "detailed basin map" button. All part of the English River system, headed to Hudson Bay by way of Lake Winnipeg. |
