Lake Summary

Little Floyd Lake is a 214-acre lake with a maximum depth of 34 ft.  It has a moderately developed shore.   Little Floyd sub-watershed area is approximately 342 acres including surface water area.  Little Floyd receives most of its water from North Floyd, which outlets to Little Floyd through the Becker CSAH 21 road, though there are some small natural drainage ways that lead to the lake.

The littoral area (< 15ft depth) of the lake accounts for 95 acres (45%) with an extensive emergent (cattail and hardstem bulrush) vegetation area located on the northeast side. There is also an abundant native plant community, with no known invasive species. There is one MN DNR public access on Little Floyd located on the south end.

Little Floyd Lake is classified as a mesotrophic lake based on the Tropic State Index average for phosphorous, chlorophyll-a, and water clarity.  In-lake phosphorus concentrations can vary between 20ppb to 34ppb and are highly responsive to storm-event and heavy rainfall patterns. The 10-year (2008-2017) average is 25 ppb in-lake phosphorus concentration.

Little Floyd Lake has two outlets located on the south side. Historically, the lake had one outlet, located near the present day public access, however, a new outlet was constructed in 1919, when the Becker County Drainage System 13 was built to channelize the Pelican River between Little Floyd lake and Big Detroit lake. In 1936, the Civilian Conservation Corps (CCC) built a concrete weir dam on Becker Drainage System 13.  This structure controls Little Floyd, as well as North and Big Floyd’s water levels. The weir has a fixed crest which is set at a run out elevation of 1354.1 (NGVD 29) and is owned and operated by the MN DNR.

Little Floyd Lake upland drainage area is 128 acres consisting of grassland 64 acres (50%), forested 26 acres (20%), cultivated 19 acres (15%), and wetlands 11 acres (9%), developed parcels 9 acres (7%).

2017 Monitoring Summary

Little Floyd receives water input, as well as nutrients,  from North Floyd.  The water quality between these two lakes are very closely related due to the connectivity.  Like it’s neighbor, water clarity began very high in 2017,  with minimal snowmelt and below average spring rains.

 Decreases in water clarity were observed following large rain events.  However, there is a noticeable lag time period of several days to a week from when the rain event occurs to when the effects can be observed.  This is a stark difference to the nearly instantaneous response seen on North Floyd.  Overall, water clarity was approximately 1 foot better than the 10-year average .
