Akkarzhanka (Ukrainian: Аккаржанка) is a small steppe river in Odesa Raion of Odesa Oblast, Ukraine. The river has origin near the village of Berezan, inflows to the Sukhyi Estuary in its north-western part, near the urban-type settlement of Velykodolynske.
The length of the river 39 km (24 mi), the watershed area is 160 km2 (62 sq mi).[1] It is fed mainly by rain and meltwater, with some minor contributions from underground runoff.[1]
Species
Using kick-nets and sampling a fish pond and the Oleksandrivka Reservoir in the river in 2018, a study found several specimens of the Macrobrachium nipponense (Oriental river prawn), which is an invasive species, within the river with estimated densities of up to 15 individuals per square meter.[2] Young individuals were consistently present, indicating reproduction in the river.[2]
Status
Reports from a commission in 2023 reported ongoing drying out and siltation of the river, and that there needed to be an attempt to clear the sources that feed the river.[3] Authorities from the rural settlement of Velykodolynske agreed to develop a project for cleaning the river, increasing control over compliance with environmental protection zones, and removing illegal structures that block access to the river in order to remedy the situation.[3]
