The Lake Riley Improvement Association (LRIA) started small in 1969 with the mission to clean and preserve Lake Riley. Today the group has expanded to include social events and neighborhood activities to build a strong social network by uniting neighbors who enjoy the lake and want to preserve and protect it.

Low Water Levels

Occasionally there will be times of drought and low water levels in the lake.  
  • Be aware of underwater hazards such as rocks and branches
  • Check boat lift levels to ensure you can get on and off the lift
  • ​Move lifts out if necessary
  • Try to avoid floating boats too long in the water so as to keep zebra mussels from attaching to motors and intakes

Ice Boats

Depending on ice and snow conditions, you may see some of the ice boats zipping around the lake.  Their high-speed and quick manueverability make them a site to behold.

*Please remember to mark any large fish holes that you cut in the ice to keep everyone safe.  

Partnerships

Every season brings opportunities for Lake Riley neighbors to connect with each other. Many members are active with our Watershed District and the Southwest Metro Lakes Coalition. We have partnered with the University of Minnesota in their world-class carp study, and continue to work with them as they study the complicated balance between lake vegetation, aquatic life, and nutrients in the water.

Members of the LRIA are proud of the abundant fish, fowl and animal life that are brought together by the water of Lake Riley. Keeping the lake healthy to sustain the natural life that abounds within and around it is a priority for the Lake Riley Improvement Association. It is a cherished natural and recreational resource for the whole community.
