About Silver Lake
- 2021 Condition: Poor/Eutrophic read more
- Features: Excellent family picnic area, complete with a shelter, grills, tables and toilet building, as well as a new playground (2018). A new boat launch and pier were installed in 2017 for launching canoes, sailboats and rowboats. No lighting, no potable water. Great opportunity for families to fish from shore or by boat. The lake is home to large mouth bass, northern pike, perch and panfish. The wooded margins and the woodchip Kiranaqui trail along the creek offer the delights of hiking and bird watching, especially at the time of the spring and fall migration of warblers. Developed on 12 acres of land leased to Manitowoc County by the Franciscan Sisters of Christian Charity of Holy Family Convent.
- Boat Ramp: New ramp in 2017, 8% slope, 3 ft launch depth, boarding dock.
- Launch Fee: The daily fee is $5 and the seasonal fee is $20.
- ADA Accessibility Features: No. Not ADA accessible. The slope to the boarding dock exceeds the maximum allowable for ADA purposes.
- Restrictions: Electric motors only by Newton town ordinance.

Stocking and DNR Surveys
|DNR Species Summary (2015):|
|species||Number||Length (ave.)||Number||Length (ave.)|
|Black Bullhead||101||5.7-14.5″ (12.7″)||3||3.6-13.8″ (10″)|
|Walleye||18||9.9-25″ (19.2″)||3||13.9-20″ (17.3″)|

|Yellow Perch||279||4.4-8″ (6″)||141||4.7-8″ (5.4″)|
|Brown Bullhead||17||12.4-14.3″ (13.1″)||1||7.4″|

|Black Crappie||15||6-10″ (6.8″)||2||3-3.2″ (3.1″)|
DNR Conclusions from 2015 Survey:
- Northern Pike numbers high despite the 2014-2015 winter kill. Size minimum regulation is working to produce an excellent Northern Pike fishery. Growth rate greater than state average.
- Winter kill severely reduced Walleye numbers and eliminated nearly all Bass. Recommended to continue stocking Walleye on an alternate year basis and Largemouth Bass for three consecutive years.
- Recommend working with lake and county residents to explore options to reduce the number and severity of overtopping events that have plagued the lake since 2004 and to address the low dissolved oxygen levels during winter months.
- Recommend monitoring invasive species, including Eurasian Water Milfoil.
- No carp captured but large carcasses noted.
- Over 1000 Double Crested Cormorants noted roosting on trees surrounding lake during survey

Condition: POOR (2021) Source
- 5-Year Average Trophic State: 62/Eutrophic
- Secchi Disk: Average summer reading for 2021 not available. (SE Georegion average 6.5 ft.)
Average summer Chlorophyll 39.7 µg/l (SE Georegion average 20.9 µg/l).
Average summer Total Phosphorus 79.5 µg/l.
May experience noticeable algae blooms.
- Trophic State Index (TSI): 63/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 blue-green algae become dominant and algal scums are possible, extensive plant overgrowth problems possible.
