is not the second largest lake in Rwanda, but it also enjoys a high degree of protection, owing to the fact that it sits in the aforementioned national park.
According to www.globalnature.org the main threat to this revered Rwandan lake is water hyacinth, which the lake has in abundance. Water hyacinth is an aquatic plant that multiplies at a high rate, and is known to be unlikeable to the areas outside its native range.
Therefore, the presence of the water hyacinth on this lake is not just as a serious threat to the biodiversity of the region, but it also hinders water transport.
Its damaging effects, among others include, lowering the quality of water because it covers the water and reducing the quantity of dissolved oxygen, phosphate and temperature, resulting in the direct decrease and disappearance of biodiversity of the affected water body.
Additionally, the lake is connected by the Akagera swamps with the Akagera river, which implies that this water hyacinth could be easily spread into nearby waterways such as Lake Victoria and the Nile River
A boat cruise on this lake will give you the opportunity to see a variety of aquatic life like birdlife, elephants, hippos, and crocodiles.
However, since Lake Ihema is not that blessed with a plethora of fish types, yes should only anticipate seeing a few of these reptiles here and there.
In any case fishing is highly restricted on this lake. In spite of all this, your sightseeing expedition on a boat cruise on this lake will still be rewarding undertaking
