Good weather leads to a growth spurt
Essen, Germany, May 28, 2026. The unusually warm temperatures of the past few days have affected the Elodea, also known as Waterweed, This gives the plants an early growth spurt. In many places, the plants are already reaching almost to the surface of the water again – and thus causing problems for water sports. Baldeneysee.Ruhr calls for caution and mutual consideration.
Increased attention for rowers, canoeists, sailors
A local water sports club is strongly warning its members about the consequences of the rapid spread. A statement reads: „Elodea is currently spreading quite strongly again. We would therefore like to ask you to be particularly attentive to oncoming boats.“ The area between SKS and SGB is particularly critical, where boats traveling upstream sometimes have to move far into the middle of the lake. This puts them in the path of boats traveling downstream – a bottleneck that is further exacerbated if an Albano system is set up for regattas. Experience from previous years shows that the risk of collisions, including between rowing boats, clearly increases with the increasing spread of Elodea. The club therefore appeals for mutual consideration and increased attention.
What water sports enthusiasts should note now
| Notice | Recommendation |
|---|---|
| Observe the fairway | Recognize crop fields early |
| Announce the evasive maneuver early | Especially in confined areas |
| Adjust speed | Avoid collision |
| Strengthen communication between associations | Joint route agreements |
| Check the regatta course regularly | Check safety and condition |

Mähboot „Insatiable“ likely to deploy soon
The municipal mowing boat „Nimmersatt,“ which was still docked in Scheppen harbor yesterday, is likely on the verge of its first deployment given the current situation. The boat is usually deployed once the plants reach the water's surface to keep shipping lanes and training routes clear. The operations are demanding: the Elodea plant grows back quickly, and especially in warm summers, the mowing boats on the Baldeneysee in constant use.
Regattas are coming up
The problem by no means only affects training operations. Several events are imminent: the Wednesday sailing regatta is weekly and already underway. The German Junior and Age Group Rowing Championships 2026 will soon take place on the Baldeneysee, followed by the West German Canoe Championships from July 17th to 19th, 2026. For regattas, the courses must be clear, safe, and easily navigable. Even a few centimeters of plant growth can slow down, damage, or even capsize boats. Organizers and clubs are therefore certainly hoping for swift measures.
Why Elodea grows so fast
Elodea is an invasive aquatic plant that thrives particularly in warm, nutrient-rich waters. The [River Name] has offered ideal conditions for several years: high water temperatures, low current, sufficient sunlight, and nutrient input from the catchment area. As soon as temperatures rise, the plant begins to grow rapidly – often several centimeters per day, reported [River Name].
