Great Movies from the NYPA and ASDSO

Here’s the latest on the safety measures for Perinton

With Mike Caswell!  Erie Canal Neighbors Association

This second video will give you a good idea of what is coming to the Perinton dams later this year.

Stage one will be the removal of all vegetation from the outboard slopes of the dams.

Stage two will be to restore privacy and other issues to residents living adjacent to these dams.

With Doug Kucmerowski Erie Canal Neighbors Association

This movie demonstrates why it so important to do this work. All folks living adjacent to these dams are in a Flood Hazard Zone.

 

Here’s what the Perinton Dam looks like  at present. Mike Caswell’s amateur video showing his perspective of the dam from 31f to The Oxbow.

Culvert Washed Out in Recent Storm

Last night, we had a strong thunderstorm, and the culvert flowing through the Oxbow feeding the canal was washed out.

The ‘bridge’ over the culvert is the old towpath for the original canal. The water flows from Minerva Deland school playing fields into The Oxbow Lake.

This structure been recently refurbished using plastic pipes, as the old ones were rusted out.

See the repairs here   

Seeing as how this is a new repair, how did this happen after only ONE heavy storm?

It’s the overall design that is at fault. These small pipes simply dam up the exit with debris that naturally falls into flooding streams. IMG_3729

The water can’t escape, and so it flows over the top of the trail.

The next problem is that no rip-rap or concrete barrier was placed on the upstream side of the trail, so scouring of the gravel took place.

Small particle size gravel was used as fill over the pipes. This tactic was used before and rocks about 6″ – 8″ were used, and these washed out.

After every rain storm, The Town of Perinton staff visit and remove the debris. Unfortunately, they don’t take it away, and leave on the side of the culvert, where it washes back  and clogs the pipes  again.

Perhaps the answer is to remove these pipes and simply replace them with a wooden footbridge? There would be much less maintenance and it would prevent motorized vehicles from accessing the trail?

This is a classic case of a culvert becoming clogged with debris and subsequently over-topping.  It just took one thunderstorm.  Imagine if this had been on a canal embankment dam culvert or spillway. The dam overflows and the soil is easily washed out – scouring.  A couple of hours of this and an embankment dam would fail.

Updating this post July 24th 2018

Last night’s heavy rainstorm caused more damage to our culvert. Much soil was eroded from one side where the culvert is lined with concrete. Scouring has occurred behind the wall, which will eventually collapse.IMG_3840

Another hole has appeared more centrally and a great deal of gravel has been washed away.

A lot of bedrock is now exposed at the upstream side of the culvert tubes, and of course, they are partially blocked by debris.

I would guess that another rainstorm will wash out the area completely. At least it  will make pipe removal a simple process!

UPDATE 8 14 2018

A huge rainstorm washed out the rip-rap, pipes and gravel completely today.

UPDATE 8 15 2018

All traces of bridge – gone!

Here’s the old pipes.

What are you putting in the canal?

There are many things that shouldn’t go into the canal, but most people have no idea why.

Canal water is a vital source of irrigation to many farmers and homeowners growing their own produce.

A trip along the canal in a boat will reveal, if you are observant, many small pumps installed along the shoreline. These are used to irrigate lawns, vegetable gardens and farms growing the produce you probably buy in places like Wegmans or Tops. These retailers love to use local producers as it supports the economy and everyone benefits.

So, imagine someone spraying a toxic chemical on vegetation along the shoreline with scant regard to the over-spray contaminating the water.  Fertilizer excess on lawns and fields, causing it to run off into the canal causes nitrogen excesses resulting in algae blooms and more. Throwing the odd bit of dog poo in, allowing Canadian Geese to contaminate your lawn, feeding them and ducks etc. etc.  It all adds up to a nasty soup in the canals, which has caused a major outbreak of E coli in romaine lettuce sold across the nation.

We need to be more careful and realise that our canal water needs to be kept cleaner!
