AquaExtension Fact Sheets

Need assistance managing fish, wildlife, aquatic vegetation, or water quality on your ranch, property, or pond? Simply call your local County Extension Agent.

Successful pond management involves more than responding when a problem appears. Aquatic vegetation, water chemistry, and fish populations all interact to influence pond dynamics. Properly identifying the source of a problem is the first step toward selecting an effective and appropriate management strategy.

Use the following AquaExtension fact sheets and publications to learn more about aquatic vegetation management, water chemistry, and general pond management. Check back frequently as new resources are added.

General Pond Management

Good pond management requires planning throughout the year. These publications provide guidance on evaluating pond conditions, preventing common problems, and completing management activities when they are most effective.

  • Timing of Pond Management Practices
  • A Landowner’s Guide to Aquatic Site Visits

Aquatic Vegetation Identification and Management

Aquatic vegetation can provide important habitat and food for fish and wildlife, but excessive or invasive plant growth may interfere with recreation, water access, and pond management goals. Because control options vary among species, aquatic plants should always be properly identified before a management plan is developed.
