The KBS Experimental Pond Facility contains 18 experimental ponds, two holding ponds and a reservoir. Each experimental pond is approximately 30 m in dia. with a maximum depth of 2 m and is lined with vinyl plastic to prevent seepage losses.

Each pond has a drain controlled by a butterfly valve, and a gravity-fed water distribution system supplies each pair of ponds via a water hydrant.


The water source is a deep well which pumps into the reservoir where the water is conditioned before entering the ponds. Drainwater is piped to a discharge site. Thus, each pond can be easily drained and refilled, allowing for experimental manipulation of the entire pond community. The two larger holding ponds are similar to the experimental ponds and are used for culturing fish stocks, zooplankton, and aquatic insects, and as sites for smaller-scale enclosure (bag) experiments. The design and construction of the ponds ensures maximum uniformity in exposure, water, and basin configuration.
