Old-times discovery of Iida river!
Studies on the relationship between people in Suwa and the river
We studied about race at the social studies class and learned that people used to use the water of the Iida River for various things. We also found that older generation, like our grandparents and parents, played in the river more often than now we do.
About agriculture in the past and its difficulties
We interviewed our parents and other people how they used the water of the Iida River in the past.
|
What kind of plays they did in the river.
- Swimming
- Fishing and catching fish
- Diving
|
How they used the water of the river.
- Farming
- Bath
- Washing clothes
- Floating ornaments for the Star Festival

The second half of the Edo period - Showa of the 50s
- Since Nakae-yousui(water system) once passes to Iida river, It intake and used in the Masago floodgate(the reverse side of the present postmaster's house).
The Showa 50s - present
- It is directly used from Nakae-yousui as Yousui to the rice field. It is
leading water from the Sasagamine dam.

The voice of the children
- People in the past played a lot in the river, but now what we can do is
only fishing or making a base. Maybe it is because people now think playing
in the river is dangerous and some are prohibited.
- We'd like to swim in the river like they did in the past.
- It must have been inconvenient without waterworks. This is why they needed to use water of the Iida River.
- We also float ornaments for the Star Festival in the river still now.
- I heard that the Iida River dried up because of the persistence of dry weather in summer and people could not use water for farming. They had many difficulties in the past.

A simple question: Why the water of the Iida River is so muddy?
It could be because the water is polluted, or are there any other reasons?
The children have been wondering about this since beginning. So we asked the civil engineers about this.
They said it is;
- because of clay in the riverbed
- because of landslide soil
- because of draining from the quarry
The research on the upper Iida River in Makimura
In September we went to Makimura to serve also as Independence PTA the upper Iida River there. The river there was very different from the river near the school. We could not get into the river in Suwa, but in Makimura we could go into the river.
It was especially great that we could visit the water purification plant
there. They said the water of the Iida River is used as drinking water
after purified.
The studies at the upper Iida River
| "Are there any aquatic animals?" |
"The river here is very different from one near the school.
I feel great standing on a stone here." |

The studies at the water purification plant in Makimura
- "I didn't know the water of the Iida River is used for drinking. The water here must be clean."
- "The purification system here is different from the one we saw at the ‘æˆêwater purification plant that we visited in spring.
- "This purification system is the best way to make tasty drinking water. I'd like to taste it!"
