Wilstone -2.02m
Startops -2.56m
Marsworth -0.14m
Tringford 0.26m
The work at Whitehouse is the first stage to move the paddle out of the channel to enable WAT to continue with their lining works. The waters will continue to drop into Wilstone.
Startops at a low level and will remain at that level, Marsworth is being used to feed the main line below Lock 39. It uses the same gauging chamber.

Wilstone -1.16m
Startops -2.42m
Marsworth -0.15m

Tring Pumping Station Status 27th July 2015.
Wilstone -0.68m
Startops -2.2m
Marsworth -0.14m
Tringford 0.22m
Boat traffic reasonably high. We are watching the reservoir stock closely now as they are below the long term average for this time of year. Heavy demand on the main line going north has meant using Startops more. (With thanks to John Kearsey of the Canal and River Trust)

Tring Pumping Station Status 15th June 2015.
Wilstone -0.18m
Startops -1.72m
Marsworth -0.05m

All looking healthy for boating needs this year. (With thanks to John Kearsey of the Canal and River Trust)

Tring Pumping Station Status 20th October 2014.
Wilstone -1.86m
Startops -2.26m
Marsworth -0.16m
Tringford -0.18m
Wilstone has risen 6” from last week. Partly though not pumping and partly as a result of cutting of vegetation on the Wendover Arm which is allowing better flow through to the pipe intake at Drayton.
Crassula Helmsii has been treated on the mudflats at Wilstone and Startops some success. Further application of approved chemical dependant on weather and water levels.(With thanks to John Kearsey of the Canal & River Trust.)

Tring Pumping Station Status 19th September 2014.
Wilstone -1.7m
Startops -2.1m
Marsworth -0.16m
Tringford -0.14m
Wilstone is lower than long term average but not worryingly so. In 2011 we were at -2.3m getting down to -2.5m in October which was about as low as we can get without taking special measures to protect the flora and fauna.

Tring Pumping Station Status 31st August 2014.
Wilstone -1.44m
Startops -1.5m
Marsworth 0.06m
Tringford 0.07m

Tring Pumping Station Status 28th July 2014.
Wilstone -0.84m - Taken a hit over the last couple of weeks. We are pumping on this to meet the summer higher boating demands
Startops -1.02m  - Reasonable for this time of year
Marsworth 0.00m - On weir
Tringford 0.07m - Being kept reasonably high pumping to keep it just off weir.
(With thanks to John Kearsey of the Canal & River Trust.)

Tring Pumping Station Status 8th June 2014.
Wilstone + 0.070m
Startops -1.180m
Tringford  +0.100m
Marsworth - 0.020m
The groundwaters are still high resulting in us not having to pump very much. It is unusual for Wilstone to be above weir at this time of year.
(With thanks to John Kearsey of the Canal & River Trust.)

Tring Pumping Station Status 9th May 2014.
Wilstone + 0.100m
Startops -1.000m
Tringford  +0.100m (note  Tringford’s zero has been adjusted to the overflow weir in the chamber in the middle of the res)
Marsworth + 0.040m
Wilstone still spilling over weir and the general water situation is that we are only pumping part time from Tringford or Wilstone. Higher boat numbers not expected until the end of May holidays.
Rain forecast over the next week too

Tring Pumping Station Status 24th March 2014.
Wilstone     +0.17m
Startops      -1.3m
Tringford     -0.28m
Marsworth +0.06m

Levels being juggled and Wilstone showing slow rate of decline of height over weir. There are high flows along the Aylesbury arm.

Tring Pumping Station Status 15th February 2014.
Wilstone     +0.22m – Overflowing at the rate of 475 litres a second!
Startops      -0.90m
Tringford     -0.50m
Marsworth +0.1m

Tring Pumping Station Status 15th January 2014.
The amounts of water are central to my thoughts at the moment. Reservoirs are full, we expect Wilstone to start weiring in the next day or two. As a group they filled by 110 mega litres week before last and by 350 Ml last week.

Wilstone     -0.140m – but expect to be zero v soon
Startops      -0.70m (we do not hold the reservoir much above this level if we can help it)
Tringford     -0.30m
Marsworth +0.07m

Tring Pumping Station Status 23rd December 2013.
No water is being pumped from Wilstone as the Number 3 pump set is down for maintenance again with the other unit requiring a new thrust bearing to be replaced. This will be out of action until January. The siphon is still being used to take water to the Aylesbury arm.

Monday's levels were:
Wilstone                       -1.50m
Startops                       -1.80m
Tringford                       -0.40m
Marsworth                     0.03m

(With thanks to John Kearsey of the Canal & River Trust.)

Tring Pumping Station Status 16th December 2013.
Monday's levels were:
Wilstone                       -1.69m  rising under control. Syphon feeding the Aylesbury Arm
Startops                       -1.86m
Tringford                       -0.36m being held at approx. this level
Marsworth                     0.03m

(With thanks to John Kearsey of the Canal & River Trust.)


Tring Pumping Station Status 17th November 2013.
Monday's levels were:
Wilstone                       -1.60m  rising under control. Syphon feeding the Aylesbury Arm
Startops                       -2.06m  grouting completed to eastern corner near to the trench sheets
Tringford                       -0.30m being held at approx. this level
Marsworth                     0.04m resin grouting to cure seepage near the auxiliary weir completed. This should dry up puddles on towpath.

The Aylesbury Lock 12 is planned for opening at the end of this month.

Tring Pumping Station Status 15th October 2013.
Monday’s levels were:
Wilstone: -1.55m  taking majority of pumping to summit, boat usage is now tailing off. Syphon feeding the Aylesbury Arm
Startops: -2.28m
Tringford: -0.25m
Marsworth: -0.12m recovering to weir level  

(With thanks to John Kearsey of the Canal & River Trust.)

Tring Pumping Station Status 18th September 2013.
Strategy for water management for the Tring reservoirs remains unchanged this month.Monday’s levels were:
Wilstone -1.20m  taking majority of pumping to summit
Startops -2.10m  we are doing some maintenance grouting on the Startops headbank this week to fill minor erosion holes.
Tringford -0.30m holding at this level, pumping to summit or spill to Wilstone
Marsworth -0.50m has been lower over the last month, looking to recover to weir level 
18th Sept: Ongoing repairs to the bank at Startopsend. They are drilling into the concrete to fill under with grout to prevent water eroding under the bank.

Tring Pumping station Status 28th August 2013.

No real change in Tring water strategy. 

We will continue to pump from Wilstone as the main source. Tring Drainage water being used to let Tringford recover. Once up to level we can then divert to Startops to ease the end of season burden there.

As of yesterday reservoir levels compared to weir level:
Wilstone             -0.64m
Startops             -2.16m
Tringford            -0.26m
Marsworth         -0.30m

And to give an indication of groundwater levels Cowroast borehole is at -4m compared with -5m this time last year.

Tring Pumping Station Status 7th August 2013. 

I can confirm that the number 3 pump set has been repaired and started pumping from Wilstone Reservoir on Monday 5th August. At the same time the Number 1 Pump which takes water from Startopsend and Tringford reservoirs was turned off. It has already been noted that Wilstone is no longer over flowing and some rocks along the bund are starting to be exposed.

The result of this should be a lowering of the levels at Wilstone and a gradual recovery of the the levels at Tringford and Startops.

The pipe taking water under the dry canal from the Wendover Spring is being diverted into Startopsend.

Hopefully a lower level will expose some mud to encourage visitors during the Autumn Migration.

Tring Pumping Station Status 13th July 2013. 

Following a recent visit, I can report the number 3 pump set is still under repair but is scheduled to be functioning by the end of July. The failure of a thrust bearing has meant it has been out of action since earlier this year. This pump set is the main pump for Wilstone reservoir and is the reason the water levels have remained at overflow. Once operational the plan is to stop pumping from Startopsend Reservoir and begin lowering the water level at Wilstone. Pump 3 consists of two pumps working together to lift the water over 70 feet to the level of the Wendover arm and to the Tring summit. 

Hopefully a lower level will expose some mud to encourage visitors during the Autumn Migration.
