River description:

The navigability of upper flow of Jizera river is depending on period of snow-thaw, it is in April and  May The river is navigable after strong rain as well. Owing to the fact that  in Jizerské Mountains are missing  the forests , the river collects quickly the water and  flows off smoothly. The number of days when there is plenty of water in  river-bed, has increased, but the navigation-period became shorter. The navigability can be followed according to water-index in Železný Brod, where the indicator over 160 cm  can present the navigability of upper Jizera from Mýto or Vilémov, the indicator 110 cm the navigability from confluence with Kamenice-river. When the water-index presents more than 180 cm  you can drive from the uppermost section. The value of water-index is influenced by Kamenice-river and on the fact if the water is let flow from  Josefův Důl-Dam. The navigability of the upper flow could be judged also according to water-index on bridge-pillar called „Na Mýtě“ , where 40 cm is a minimum, 60 cm is an optimal stand, and  more than 80 cm the difficulty is increasing of one stage. The river has a character of Alps rivers, speed of stream is great and the water rollers are kept.  The indication of 40 cm of water-index corresponds the indicator of water-index in Jablonec nad Jizerou. You can drive from this point when the water-index shows 30 cm. In the uppermost section – from Jizerka to railway-bridge – the river forms the state border with Poland , therefore could be some problems with the navigation. In the section from Mýto up to Jablonec the river flows through KRNAP (Giant Mountains Natural Park), there are signed the places where it is possible to enter the river. Under „ Island of  Horror“ ( it is a name of difficult place , 1, 5 kms distant from Mýto), it is  constructed the access path to the river from the main road. Attention on the passing cars, as there is no place for parking !(you have to stop and park along the road !) You find the other similar places in Vilémov and Paseky. All suitable places are marked with plates  of waterman-picture. It is worth to respect these places. Except National Park the river flows, near the town of Semily, through Natural Park „Jizera Valley“. There is , however, limited access to the river. The navigation speed on the section from Jizerka II to the „ostrov-Island“ is for experienced and well equipped  watermen 4 kms only. You have to investigate first and secure the difficult  places (especially the section from Kořenov-bridge to Mýto and the passes near to Ostrov).

Further, the only obstacles there are the weirs, at several of them it is necessary to carry over the boats. You can calculate with the time of 6-8 kms in an hour , this is valid up to Semily. The section  of „Rieger Path“ is recommended to be investigated first. The average speed in the plain part is  5-6 kms per hour.

Jizera belongs to rivers of mountaineous character and is very popular with with watermen who navigate more difficult rivers. It springs in Poland  near to the  state border  on slope of Smrk and enters the Bohemian territory in an alzitude of 885 m of sea level.  It forms border-flow up to the community of Kořenov. Further, it flows to the south and southeast, near to Jilemnice it turns to the west and the direction keeps till its mouth into Elbe at Toušeň.

Its river-basin makes 2193 kms. From its spring, Jizera flows throughout table-land  among peatbogs, and under Bukovec  enters into enclosed valley , with boulders, cascades and high stages , forming the rapids of highest difficulty. In this section, the river creates the border of Giant Mountains National Park. Its slope as well as difficulty decreases subsequently towards the town of Semily. There are more often the weirs on the river, which are not navigable, however. Near to Semily the rive squeezes through short  pass , along the banks leads well known touristic „Rieger Path“. Further to the town of Turnov, the  river flows with its activ stream, and from Turnov it is a plain-river with moderate stream. The stream is quicker before its mouth to the Elbe-river, near to the town of Benátky. The river-bed is in its upper flow wide 10-20 m approx. , whereas on its lower flow  reaches ithe width up to 50 m.

The river is surrounded by forests in its upper flow. Further, the river flows through meadows with willow trees on the banks.

Jizera-river has several navigable tributaries , the biggest is Kamenice, further Mumlava, Jizerka I, Jizerka II, Oleška, Žarnovník, Mohelka.
