Weed and algae overtaking pond
Im wondering what can be done to safely and economically get rid of some of the weeds and algae in our two ponds. Both are spring fed and one pond also feeds the other.
Ottawa County Michigan
Here a re a couple steps to take:
- Identify what species of plants are in your pond
- If they are invasive, herbicide is a typical management option to control their growth.
- If the plants are native, then consider keeping some because they are beneficial. Here is a great article on the benefits of aquatic plants and how to manage a more desirable coverage: https://senr.osu.edu/sites/senr/files/imce/files/extension_outreach/ponds_fish_aq_mgmt/Autumn2017.pdf
- Prevention. Prevent nutrient runoff from entering your ponds. A buffer of vegetation around the pond can go a long way. However, you can also implement a no application zone around your ponds. This will help reduce any fertilizer runoff from entering your pond.
- Here's a great resource that gives many algae and plant control techniques: https://archive.lib.msu.edu/DMC/Ag.%20Ext.%202007-Chelsie/PDF/e1554-1994-print3.pdf
