Officials Aim To Improve Water Quality In Northwest Iowa Lake
Iowa’s Department of Natural Resources is working on finalizing a plan to improve a northwest Iowa lake plagued by poor water quality.

The 1,000-acre shallow lake engulfed by a 17,000-acre watershed struggles with water quality because the amount of land mass that surrounds it sends a lot of nutrients to the water. Severe algal blooms caused by phosphorous plague the lake over the summer and can create toxins that can be an issue for human health.

One of the solutions Bischoff mentioned is planting aquatic vegetation in the lake that will uptake the nutrients. A resident expressed concerns that having too many plants in an area of the lake would make it difficult for boaters.

Ecological Value of Exotic Water Plants Equals that of Indigenous Species - If you look at the role of exotic water plants in an ecosystem, you won't find any significant differences compared to indigenous species. Researchers studied seven essential functions of water plants in experiments with indigenous and non-indigenous species. They looked among other things at the impact of the plants on the habitat and food supply of fish and small aquatic animals, on cyanobacterial growth and on greenhouse gas emissions. What they found was that all things considered, the two groups are not fundamentally different.
