Fishways are structures which allow fish to move over or through dams and weirs. They act as a ladder allowing fish to climb up or down a channel designed to accommodate their swimming ability. The speed of water in a fishway is controlled to suit the species and size of fish likely to use it.
Lock fishways operate by attracting fish through an entrance similar to that of a pool-type fishway, but instead of swimming up a channel the fish accumulate in a holding area at the base of the lock. This holding area is then sealed and filled with water to reach a level equal to the water upstream of the barrier. Fish are then able to swim out of the lock. To encourage fish to move through the various attraction and exit phases of the lock cycle, a combination of attraction flows and crowding screens can be used. There is a fish-lock fishway on Balranald Weir on the Murrumbidgee River.
A pair of Warner & Swasey 6x21.5 binoculars. They are marked with a patent date of 18 March 1902 ( this refers to the Gottlieb Fecker “Porro prism telescope and leaf spring prism clamp”, and have a serial number of 27622; this is in the same font as the British government binocular grading (see below), so is probaly a military serial number. Between 1900 and 1918, when they stopped producing binoculars, they manufactured around 6,000 pairs in 6x, 8x, and 10x, many of them for the US Navy, their first prismatic binocular. The retail price was $40. This pair is marked with the British Government broad arrow, meaning they were purchased by the government early in WW1 for issue to the army, along with many French binoculars.
These purchased binoculars were marked with “S.1-6”, the number denoting the grade and type of binocular, prismatic, Galilean, unusual. This Warner & Swasey pair is marked S.1, indicating “high grade, prismatic”. The other grades were S.2, second grade prismatic; S.3 high grade Galilean; S.4 second grade Galilean; S.5 third grade prismatic or Galilean; S.6 unusual design.
The bodies have two strap loops, front and rear, and the front bridge boss has a hole to accept a tommy bar to lock the inter pupillary distance, like a pair of 1912 Zeiss Telex in my collection. Inside the case are two slots, one with a pocket for the tommy bar, which is absent. The case is military style, with a belt loop.
Warner & Swasey, known more for astronomical telescopes and turret lathes, was established in 1880 and were taken over in 1980 by the Bendix Corporation. During the 1886 Spanish-American War, they produced optical equipment such as rangefinders and gun sights. They also produced a prismatic telescopic rifle sight which was still in use in WW2.
The lock building, looking very much like some sort of rural railway station - an image furthered by the fact that the lock building sits on an island, meaning that it looks a bit like it has platforms on both sides of the building.

Wonder if Mahsoo & Vishal are still "locked" in love. ;)
This padlock is on the hide at Holland Haven, one of my local nature reserves. I'm not really sure if I'm even supposed to go there for my exercise under the current lockdown. Hopefully things will start to improve soon!

Torksey Lock sits just back from the River Trent, from here it connects with the Fossdyke.
The Roman built Fossdyke dates back to 120AD, making it the oldest working canal in England.

I'm locked up, they wont let me out, they wont let me out.
ok, I dont know why I thought of Akon's song but I did.
I think I got lucky. This is the first time ever saw this. They were locked in the mating position for a long time, flapping their wings occasionally.
