threepwood Posted April 28, 2020 Share Posted April 28, 2020 Is it just me, or is the flow rate data for basically every river missing from the AB Rivers app and website right now? I asked someone at AEP today and they said a gauge was broken, but I think they meant on the Athabasca up at Ft. Mac. Just wondering if I'm having amazing levels of user error, or if the data isn't showing up yet. Trying to watch for when those flows start to come down...

Wrighter Posted April 28, 2020 Share Posted April 28, 2020 You're definitely correct, mostly just water levels being displayed everywhere. I'm not sure what's going on either but it would be nice to see some flow rates! Quote Link to comment Share on other sites More sharing options...
FraserN Posted April 28, 2020 Share Posted April 28, 2020 I am having the same problem. It sure would be nice to know the flow rate of the Bow river in Calgary right about now. Quote Link to comment Share on other sites More sharing options...
eagleflyfisher Posted April 28, 2020 Share Posted April 28, 2020 Are you using RiverApp, shows flow rates on mine. Quote Link to comment Share on other sites More sharing options...
bcubed Posted April 28, 2020 Share Posted April 28, 2020 Flows are just from a calculation using water level, from what i understand, so any missing flows are likely a software issue if they're still reading water levels. I noticed that the Elbow one randomly turned on last week, so wouldnt surprise me if they need someone manually to hit a 'export flows' Quote Link to comment Share on other sites More sharing options...
dwday Posted April 28, 2020 Share Posted April 28, 2020 The flow rates start showing on there around late April or early May. Every year seems different 1 Quote Link to comment Share on other sites More sharing options...

DonAndersen Posted May 1, 2020 Share Posted May 1, 2020 The water level measurement device is housed in small buildings where the measurement device freezes and therefore not accurate for <> 7 months. Don 1 Quote Link to comment Share on other sites More sharing options...
dwday Posted May 1, 2020 Share Posted May 1, 2020 Don is right. The have to recalibrate some of the stations in the spring Quote Link to comment Share on other sites More sharing options...
dwday Posted May 1, 2020 Share Posted May 1, 2020 Don do you know if the stations have to be turned on manually each year or are they done remotely? Quote Link to comment Share on other sites More sharing options...
TightLinesJ Posted May 1, 2020 Share Posted May 1, 2020 Just looked, and the flow data is up now............at least in my neck of the woods, and north to west central alberta Quote Link to comment Share on other sites More sharing options...

DonAndersen Posted May 3, 2020 Share Posted May 3, 2020 I’ve watched the technicians calabtprate the system by first measuring the profile on the stream, determine velocity and measuring the level. I would imagine there is some type of calculation applied. As the levels change, so does calculated flow rate. However, and don’t you must love howevers. 1) this assumes stream contour remains the same. Over winter, depending on ice formation, stream contours may change. 2) the level device must be free to move. Ice impedes level device. As most of these stream flow samplers are located tight to the stream, ice would take som time to disappear. Tbe takeaway, use the information as an ABOUT flow and not exact.

porto Posted August 6, 2020 Share Posted August 6, 2020 Good morning, looking at the flows this morning, something doesn't seem right. Flows level from midnight to 8:00am this morning has dropped a dramatic 180 m3/s to 105 m3/s. I’ve never Witnessed such a large volume of a drop in a short period of time. Is this actually the case this morning? Or maybe a error on the software at the Alberta Rivers Flow charts App... and if so, wondering how the fish would be affected in a short time environment.

You need to spend more time watching flows and being annoyed at Transalta if this is the first time you've seen that on the Bow.. I can tell you right now, you would not want to be guiding on days like this. if the river has a 'shut-off' button, a drop of 80 m3/s is likely it. 2 Quote Link to comment Share on other sites More sharing options...
bcubed Posted August 6, 2020 Share Posted August 6, 2020 Best of all, WID is still running full tilt, meaning flows at Policemens around 75 cms.. gideeeyup 1 Quote Link to comment Share on other sites More sharing options...
monger Posted August 6, 2020 Share Posted August 6, 2020 Lost about 12" of water overnight. Very natural...... Quote Link to comment Share on other sites More sharing options...
porto Posted August 7, 2020 Share Posted August 7, 2020 Well it’s spiked up to 165 m3/s now. So they basically raised And returned the 12” of water level back from what we lost over night. This is borderline criminal! Quote Link to comment Share on other sites More sharing options...
bcubed Posted August 7, 2020 Share Posted August 7, 2020 “ Response from Transalta: my request for who at AEP asked for drop was ignored. Hello Thank you for your email, I am writing to provide some context surrounding the changes to river flows that occurred on the Bow River upstream of the Calgary Weir on the morning of August 6. The flows in reference were the result of a request from Alberta Environment and Parks (AEP) to assist in re-installing a safety boom upstream of Calgary Weir. The flows were decreased to ensure safe conditions for workers installing the safety boom, and were returned to normal (approx. 150 cms/hr) following completion of the project at approximately 1 p.m. on Thursday, August 6. The flows were reduced as per our operational standard of 15 cms/hr, beginning at 12 a.m. on August 6. We understand that the Bow River flows impact many individuals and organizations and we are working with AEP to ensure that AEP provides appropriate notices in the future to the public.” Quote Link to comment Share on other sites More sharing options...
TightLinesJ Posted August 11, 2020 Share Posted August 11, 2020 Be careful out there guys, especially if you’re able to wade out to an island. The flows can come up quick if you’re not paying attention I know from experience, that was not a fun return to shore 1 Quote Link to comment Share on other sites More sharing options...
