Part of: Lake Hiawatha Park

Lake Hiawatha is part of the Lake Nokomis–Lake Hiawatha Regional Park. The 55-acre lake in the 266-acre park has low aquatic plant growth and excellent aesthetics with access to a variety of recreational opportunities as well as a fishing dock and beach. Naturalized shorelines provide good habitat quality for waterfowl and wildlife. Lake Hiawatha has an extremely large watershed due its connection with Minnehaha Creek. The creek impacts the amount of debris washed into the lake and creates fluctuations in water levels.

About Secchi Disk Readings

To measure water transparency with a Secchi disk, the disk is lowered from the shaded side of a boat until it cannot be seen. The depth of the water is recorded at the point where the disk reappears upon raising it from its original depth beyond visibility. It is important to remember that the Secchi measurement is a simple, approximate measurement of water clarity and can be influenced by various factors such as time of day, reader’s eyesight, water color and suspended particles in the water. Therefore, Secchi disk readings should be used as a comparative tool to determine trends between lakes and over time.

  • Increased water clarity may be due to reduced nutrient inputs, seasonal algal cycles, decreased sediment inputs, and zooplankton grazing on algae.
  • Decreased water clarity may be due to large algal blooms, increased soil erosion inputs, wind circulation of sediments and nutrients, stormwater inputs, or a decrease in zooplankton.

Secchi readings for the lakes are done during the regular lake sampling schedule, with some lakes sampled every other year. Current Secchi readings taken during lake sampling can be found on the Lake Water Quality Map.

Lake Aesthetic and User Recreation Index (LAURI)

HiawathaLAURI

The Lake Aesthetic and User Recreation Index (LAURI) was designed to give recreational users an easily understandable graphical source of information about conditions affecting their use of city lakes. The goal is to have an accurate, science based and easily understandable recreational indicator for the public. The LAURI has the five following indices: aesthetic considerations, water clarity, public health, habitat quality, and recreational access. For each of the five indices, the LAURI calculates a value that is then considered poor, good, or excellent.
