Current LHA policy is to draw down the lake every 5 years giving lake front owners the opportunity to do property maintenance along the shoreline. If you have plans for shoreline work, permits/approvals will be needed in advance. Please be aware of:

 

LHA Ordinance 4-7 Lake Shore or Lake Bottom Disturbance Activity. 

a) Without approval from the Board of Governors and from the Inland Wetlands and Watercourses Commission of the town of Harwinton, no person, by use of machines or power equipment of any kind, may dig, dredge or remove soil from the Lake bottom or bulldoze or otherwise move such soil from one place to a new location within the boundaries of the Lake, as the same are marked by the normal spring water line of the Lake.   

b) Without approval from the Board of Governors and from the Inland Wetlands and Watercourses Commission of the town of Harwinton, no person may construct any retaining wall that alters the boundary of the Lake as the same now exists and is marked by the normal spring water line of the Lake.  

...and people had a good time!

 

Also, check out the CT Deep Fisheries Lake Harwinton Survey Report. On October 29, 2025 CT DEEP Fisheries sampled the fish community in the lake - at no cost - with the intention of gathering information to help us make informed decisions about stocking. Here's the report. The Board of Governors welcomes your feedback and ideas for continued stocking of the lake for fishing.
