Carstens Lake News

    Ice Fishing in Manitowoc County by Todd S. Bergmann 

    Reprinted with permission. Originally published in the Valders Journal on February 1, 2018.

    Recent innovations and technology make it easier to catch more fish, an expert fisherman told area sportsmen last week.  Tournament fisherman Clint Ward addressed a meeting of the Manitowoc County Lakes Association on Jan. 25, discussing everything from his favorite ice fishing equipment to how he beat his cousin using the latest technical advances.

    Ward said the best lakes in the county for catching: bluegills are Carstens, Weyers, West and Bullhead; for crappie it’s Long, Shoe and English; for perch it’s English; and for northerns it’s Wilke, Hartlaub, Schisel, and Cedar.  Additionally, Cedar, SilverEnglish and Pigeon lakes contain small populations of walleyes, he said.

Location/Directions: Town of Newton. Take Highway 42 South approximately 4 miles from Manitowoc to Carstens Lake Road. East .5 miles to driveway to the North.

Accessibility: 44° 1′ 25.51″ N / 87° 45′ 57.25″ W

Surface Area: 21 acres

Shorelength:  .8 mi

Depth: Max 28′, Mean 12′

Bottom: 0% sand, 0% gravel, 0% rock, 99% muck

Lake Type: Deep Seepage. Deep Seepage lakes stratify, or form separate layers of water, during the summer months and have no inlet or outlet.

RestrictionsMotorboat Prohibition: only electric motors are allowed. Slow-No-Wake Areas/Hours, Water Skiing Restrictions. Read the Wisconsin handbook

Recreational Features: Parking for 15 car/trailer units, Boat Landing, Pier, Public Toilet, Lighting.

Note: Several years ago, the DNR poisoned off the lake and a fish weir was installed within the inlet stream to block off the spawning runs of rough fish from Lake Michigan.

An active property owners’ group maintains an aeration system on this 21-acre lake. But even so, Carsten’s can suffer winterkill. The 2010 DNR survey found three dozen largemouth bass and a pair of northern pike.

Condition: POOR

  • New! View Current Water Sampling Data on the Friends of Hika Bay website
  • 5-Year Average Trophic State: 63/Eutrophic (Source: Wisconsin DNR)
  • Secchi Disk (2016): Average summer reading = 6 ft. SE Georegion average = 6.8 ft.
    Summer (July/Aug) water was reported as MURKY and BROWN. This suggests that the secchi depth may have been mostly impacted by suspended sediments, tiny particles of soil or organic matter that are suspended in the water. Shallow lakes are often turbid because wind stirs up sediment from the bottom. High suspended sediments are often found in flowages and impoundments where precipitation runoff from the watershed transports solids via an incoming stream.
  • Chemistry (2016): The average summer Chlorophyll was 23.8 µg/l (compared to a Southeast Georegion summer average of 23.5 µg/l). The summer total Phosphorus average was 49 µg/l. Lakes that have more than 20 µg/l and impoundments that have more than 30 µg/l of total phosphorus may experience noticeable algae blooms.
  • Trophic State Index (TSI) (2016): 59/Eutrophic. What does this mean?
    Eutrophic lakes are high in nutrients and contain large populations of plants, algae, and fish, which often grow to nuisance levels, and the fish species are generally tolerant of warm temperatures and low oxygen conditions. Phosphorus can fuel algae blooms.This TSI usually suggests decreased clarity, fewer algal species, oxygen-depleted bottom waters during the summer, plant overgrowth evident, warm-water fisheries (pike, perch, bass, etc.) only.
