I think John Beck's theory for the source of the main inlet in Streaks was that it took water which escapes from Watergrove Sough somewhere along its length. However, we were there when Cavendish Mill was discharging a huge amount of milky water down Farnsley Lane and down to the bend where the Sough tale emerges, joining the partially culverted stream that continues down the dale. The water coming out the Sough tale was crystal clear but the Streaks streamway that day, right the way from the main inlet, was the same thick milky water that was coming down Farnsley Lane. Which suggests that most of, if not all, the Streaks/Nickergrove water somehow makes its way into the system downstream of the Sough tale/bend in the road.
Mikey, thanks for this, that's a very interesting report! Do you know the date? How was the water getting down Farnsley Lane? Down the road? There may be another possibility in that rather than sinking downstream of Watergrove Sough Tail, some of it was sinking into Farnsley Lane Swallet and making it's way to Streaks from there. This might make more sense than any seeping through from the sough tail area or surface stream/culvert, as currently Watergrove Sough is flowing but the Merlins streamway (and so presumably the Streaks one also) is totally dry. This is one of the main reasons i'd like to know current water flow in Streaks.
In Streaks, you say Main Inlet, but there are three inlets i know of upstream of the entrance (a low bedding crawl, coming out of the wall just upstream of Alexanders Aven, and Lu Blue). Did you check any of these in particular?

Word on SUSS street is that the sumps are open between Merlin Mine and The Wonder Cave.
There are no sumps between Merlins and Carlswark. The sumps in Merlins (which
are currently dry up to Sump 5) head upstream away from Carlswark. There
is a couple wet grovels through the connection, but i don't think they sump...

If the Carlswark resurgence entrance is open, that can be quite fun, if you like watery struggling. But the central 'sough' section is worth seeing, if that's the right word. 'Experiencing' is probably better.
We did Merlins to the resurgence through trip last week, and you can do it without getting very wet. The climb down from Oyster Chamber is good fun! The central section to Stalactite Passage was still flooded last week.
And I did in Flower Pot out Merlins last night, which is also a nice through trip, and i wonder if it had been done before...
