I just did a quick search and realized the difference in MA and NH laws.
NH law: The use of lead sinkers (1 ounce or less) and jigs (less than
1 inch along its longest axis) is prohibited in all freshwater
MA law: The use of any lead fishing sinkers and lead jigs weighing less than 1 ounce is now prohibited in all inland waters (freshwater) of the Commonwealth. In terms of this regulation, "lead sinker" or "lead weight" is defined as any sinker or weight made from lead that weighs less than 1 ounce. A "lead jig" is defined as any lead-weighted hook weighing less than 1 ounce. Spinnerbaits, buzzbaits are good to go.
So if you fish in NH, don't throw away those 1/2 oz jigs. I promise you they are at least an inch long. Considering that NH which led the lead ban but isn't banning the lead jig and the loon population is pretty healthy (see
http://www.wildlife.state.nh.us/Fishing/Fishing_PDFs/Lets_Get_the_Lead_Out.pdf), I dont see why MA took it upon themselves to extend the ban. Also, I was wondering if this is any waterfowl had this problem, but considering that a lot of that lost tackle is in a little deeper water, the deep diving depth of a loon (100ft??) makes it a prime candidate to get this lure (I need to train and tie a loon on as my lure retrieval tool).
And for those who don't want to go the pdf above, some interesting facts from NH:
Before lead ban, 6 loons deaths per year (1992-1999) from lead (more from other causes I'm sure) and after 5 per year (2000-2006). Is the slight decrease from the ban? Are there still plenty of left over lead shot in the water? The number of deaths doesnt sound like much until you see that there is only about 140 nesting pairs (this may be accurate as of 2006?).
My view, its the law, I'll follow it and I agree its the right thing. But enforcing it will be tough considering there is only about 80 MEP statewide (at least thats what they told me about a year ago). Its one of the first budgets to get cut. Not sure why Lake Cochituate ALWAYS has a MEP at the launch. I've only ever seen them there and at Upper Mystic Lake launch. Plus, when he came over to check us, he asked (but we didnt have to show) our license and he did check registration. Will he check for lead next time, probably not. I imagine that this law is one that will be followed by those who want to and if you don't, you probably will never be questioned, asked, or inspected.
