It’s a fair question, and unless you’re in the know (and sometimes even if you are) it can be confusing. The current situation is that the bottom release flow was increased over the weekend…and now it’s back down. Here’s a good explanation from our friends at UpCountry: “The MDC just emailed us, the CT DEEP is providing another 25cfs from their bank of water, which means the dam release went up by another 25cfs (they were already adding an additional 25cfs to the minimum flow that MDC has been running this Summer, so now they are adding a total of 50cfs). They were releasing 96cfs (was reading 113cfs at the USGS gauge)- this morning, this increase brings the dam release up to 121cfs, and by the time it hits the Riverton gauge (about 2-2.5 miles downstream) it will read closer to 140cfs, and with about 20cfs additional water coming in from the Still River the total flow below that will be around 160cfs, putting us closer to a normal late August level (200+ cfs) this weekend. This flow bump is being done to help lower the water temps- predicted highs this weekend of 94 for Saturday, low of 72 Saturday night, 96 high for Sunday, and a low of 77 Sunday night- the heat wave breaks on Monday/Tuesday. A big kudos to the DEEP for taking this action, it will keep the entire river cooler, and especially help the downstream trout in Canton, Collinville, Unionville & below make it through this hot weather. I suspect the DEEP will drop their 50cfs contribution down to 25cfs sometime soon after the weekend, as they don’t have a very big “bank” of water to use.”
That was posted before this most recent weekend. The dam flow on Monday noon is 122cfs and the release temperature is under 50 degrees, which is fantastic. Hopefully we’ll get some rain today, which will raise the Still River (currently under 20cfs) and temporarily add some water to the system.
