Warning...Environmental policy, so it is a bit wonkish. Having worked for different divisions within the DNR( no longer), and with my research and current work in this very field, it is very dear to me.

The details for the Clean Water, Land and Legacy Amendment:

How much will it raise and what will it be used for?

The current general sales and use tax rate is 6.5%. Sales tax
revenue is deposited in the state General Fund.) It raises the state sales tax to 6.875% and dedicates the additional proceeds as follows:
• 33% to a newly created Outdoor Heritage Fund to be spent
only to restore, protect, and enhance wetlands, prairies, forests,
and habitat for game, fish, and wildlife (approximately
$80 million in FY 2010 and $91 million in FY 2011);
• 33% to a newly-created Clean Water Fund to be spent only
to protect, enhance, and restore water quality in lakes, rivers,
streams, and groundwater, with at least 5% of the fund spent
to protect drinking water sources (approximately $80 million
in FY 2010 and $91 million in FY 2011);
• 14.25% to a newly created Parks and Trails Fund to be
spent only to support parks and trails of regional or statewide
significance (approximately $35 million in FY 2010 and $39
million in FY 2011);
• 19.75% to a newly created Arts and Cultural Heritage Fund
to be spent only for arts, arts education, and arts access, and
to preserve Minnesota’s history and cultural heritage
(approximately $48 million in FY 2010 and $54.5 million in
FY 2011).

The money does not automatically go to the Minnesota DNR. It is competitive money, meaning agencies and groups propose projects which are then evaluated for funding.

Finally, some stability, and maybe some new projects and repairs...Believe me, I have my stories.
