سد لَتیان سدی است بر روی رودخانه جاجرود که در ۲۵ کیلومتری شمال شرقی تهران[۱] و در لواسان قرار دارد. این سد بتنی یکی از منابع اصلی تأمین آب تهران می باشد که ۳۰ درصد از آب شرب شهر تهران را تأمین مینماید.

این سد در جنوب شهر لواسان واقع گردیده و در محلی که رودخانه برگ جهان به جاجرود می‌ریزد و در دره‌ای در میان کوه جاجرود و کوه بندک ساخته شده و در شمال آن کوه آلون قرار دارد. دو پارک جنگلی به نامهای لتیان و تلو دریاچه این سد را احاطه کرده‌اند. رودخانه جاجرود آبریز و تامین کننده اصلی سد لتیان است. رودخانه های کُندرود (لوارک) ، افچه ، برگ جهان از دیگر آبریزهای این سد هستند.

کف دریاچه سد لتیان در ارتفاع ۱۶۰۰ متری از سطح دریا قرار دارد

راه رسیدن به این سد از تهران از طریق جاده لشگرک و گردنه قوچک یا بزرگراه تهران-دماوند است. محله هایی از شهر لواسان که در شمال دریاچه سد لتیان قرار گرفته‌اند عبارت‌اند از: سبو بزرگ، سبو کوچک، کلاک، ناران، گلندوک، جائیج، نجارکلا، ناظم آباد و شورکاب.

در جنوب دیواره بتنی دریاچه مجتمع مسکونی کارکنان سد لتیان قرار دارد و در جنوب غربی دریاچه روستای مسکونی غیرمجاز نصرت‌آباد قرار داشت که در دیماه سال ۱۳۹۱ بدستور مقامات قضایی کلا تخریب شد و ساکنان آن که همگی مهاجر و غیر بومی بودند را به ورامین انتقال دادند.

لتیان نام یکی از روستاهای زیر آب رفته است که نزدیک ترین آنها به دیواره سد لتیان بوده است. ساکنان لتیان پس از فروش اراضی خود به دولت در محله های شهر لواسان ساکن شدند.

این سد قبل از انقلاب اسلامی ایران بمانند شهر لواسان که شهر فرحناز نامیده شده بود سد فرحناز نامگذاری شد که مورد اعتراض اهالی لواسان قرار گرفت و در نهایت پس از پیروزی انقلاب مجددا به اسامی سابق بازگردانده شدند.

This is an overview of Tehran

Overview and History

Tehran is the capital of Iran and the largest city in the Middle East, with a population of fifteen million people living under the peaks of the Alborz mountain range.

Although archaeological evidence places human activity around Tehran back into the years 6000BC, the city was not mentioned in any writings until much later, in the thirteenth century. It's a relatively new city by Iranian standards.

But Tehran was a well-known village in the ninth century. It grew rapidly when its neighboring city, Rhages, was destroyed by Mongolian raiders. Many people fled to Tehran.

In the seventeenth century Tehran became home to the rulers of the Safavid Dynasty. This is the period when the wall around the city was first constructed. Tehran became the capital of Iran in 1795 and amazingly fast growth followed over the next two hundred years.

The recent history of Tehran saw construction of apartment complexes and wide avenues in place of the old Persian gardens, to the detriment of the city's cultural history.

The city at present is laid out in two general parts. Northern Tehran is more cosmopolitan and expensive, southern Tehran is cheaper and gets the name "downtown."

Getting There

Mehrabad airport is the original one which is currently in the process of being replaced by Imam Khomeini International Airport. The new one is farther away from the city but it now receives all the international traffic, so allow an extra hour to get there or back.


Tehran driving can be a wild free-for-all like some South American cities, so get ready for shared taxis, confusing bus routes and a brand new shiny metro system to make it all better. To be fair, there is a great highway system here.

The metro has four lines, tickets cost 2000IR, and they have segregated cars. The women-only carriages are the last two at the end, FYI.

Taxis come in two flavors, shared and private. Private taxis are more expensive but easier to manage for the visiting traveler. Tehran has a mean rush hour starting at seven AM and lasting until 8PM in its evening version. Solution? Motorcycle taxis! They cut through the traffic and any spare nerves you might have left.

People and Culture

More than sixty percent of Tehranis were born outside of the city, making it as ethnically and linguistically diverse as the country itself. Tehran is the most secular and liberal city in Iran and as such it attracts students from all over the country.

Things to do, Recommendations

Take the metro to the Tehran Bazaar at the stop "Panzda Gordad". There you can find anything and everything -- shoes, clothes, food, gold, machines and more. Just for the sight of it alone you should take a trip there.

If you like being outside, go to Darband and drink tea in a traditional setting. Tehranis love a good picnic and there are plenty of parks to enjoy. Try Mellat park on a friday (fridays are public holidays), or maybe Park Daneshjou, Saaii or Jamshidieh.

Remember to go upstairs and have a look around, always always always! The Azadi Tower should fit the bill; it was constructed to commemorate the 2500th anniversary of the Persian Empire.

Tehran is also full of museums such as:

the Contemporary Art Museum

the Abghine Musuem (glass works)

the 19th century Golestan Royal Palace museum

the museum of carpets (!!!)

Reza Abbasi Museum of extraordinary miniatures

and most stunning of all,

the Crown Jewels Museum which holds the largest pink diamond in the world and many other jaw-dropping jewels.
