Creek fishing in Switzerland

It was a sunny day,with a bit chilly wind...it was about 9am.
Google was kind enough to show me the map of a nearby stream around Lully,not far from Morges,in the canton of Vaud.
I'm not really sure of the direction but it's always the case with new spot,esp. river or small lake.
The journey through apple farm,grapes and peach was lovely, everybody along the way was friendly...'Bonjour' was the only word I repeated along the way.
So I reached this one corner at the end of an apple farm,with some houses in the woods,and I can hear the sweet sound,the sound of running water.So I went in the bush and found a jogging/walking track.This is a good thing in Switzerland,they always have track along a stream,river and lake for recreational use.
And there it is,a nice looking stream,about 3-4 metre wide and with small rapids.From the maps I saw in Google,this stream is called Le Boiron.
It was not long before I spot movement in the water.First I thought it was a trout,but then I notice it has scales,so it must be something else.Few casts here and it just follow and no strike.
I went up river and found a bigger pool.And a bigger fish chase my spinner,but no strike.
So I went down river...once and a while passed by some joggers...'Bonjour' again and again..and strange enough,I was the only one fishing there...I wonder if I need permit here,but I saw many signs sprayed on the trees,fish image in blue color,so I guess this area is fishable.
It passed 3 hours when I first check the time...time flies..and no strike yet...(which is normal if you fish a lot)...until lower river passed the tunnel under a railway track,in a slight deeper pool that I get my first strike,but no hook on.That gave me a little hope and courage.So I went down futher till I reached a bee farm(to make honey I guess)...and from the bank of a big pool I saw 3-4 decent size fish swimming near the surface.So I turned back upper river to find a way to cross to the other side and to find a better place to cast.I must say lure casting here is hard since there are a lot of trees and branches,and 6 feet rod is totally doesn't belong here.Shallow water also doesn't help with dead branches in the river bed.The lure stuck so many times...a bit frustrating.
So I was half squatting on a fallen tree and made the first cast to the pool.And before I reel it in,it get a strong bite and pull, I have to tighten the spool and slowly reel it in,since I wasn't confident enough with the mono line I use on this rod we got from Aldi last year.Back home I use braided line.
After one or two minutes,the fish reached the bank,and just about after 2 feets away from the water,the hook came off,and I have to jump down from the tree to make sure the fish don't get back to the water before a photo session or two.And after a few shots, I released it back to the river..
So here are some pics...

The village of Lully

At the back ground is lake Le Mann/Geneva and Alps,behind the cloud there is the great Mont Blanc,which is on the French side.

The first spot where I arrive,small but as long as there is water,I cast..

The one and only catch of the day..

The disadvantage of fishing alone,you can't get good picture of yourself and the fish.

It's a Chub or Chevaine(French)...swim up the creek from the lake since the water is warmer..

Some views along the way...

I've been told that when the birds get together,summer is coming to the end.These birds will form a big group before they head South to the high plateau in Africa.

After a long day fishing,I make myself some nice pancake with Nutella...

And a week later I went to a another river,which is bigger and known to have trout.The river is le Venoge.I got many strikes,but the fish are too small,and only two landed.One small Chub and one small Perch.And no sign of my target species,Trout.Maybe I have to go further up the river.
