A similar lake example is the semi natural Deep Creek Lake in Western
Maryland where non-native invasive Hydrilla ends aquatic tourism. $ 15
million spent to save tourism in such lakes in MD:

Our lobbyist has suggested I reach out to you two to see if you would be
willing to support ( as appropriate) our
State Lakes Protection and Restoration Fund bill-- SB 396, hearing EHEA on
Basically, DCL and the other 15 state owned lakes are in declining
conditions. DNR did not even have a list of lakes until we made them compile
it as result of our State Lakes Invasive Species Act in 2015.
There is basically no state funding for these state owned assets-- programs
are limited to Bay and or have BMPs which work for tidal waters, not lakes.
Bay funding could be available BUT DNR is not doing WIP so they are not
eligible ( Clopper Lake could benefit if they did.) DCL, the largest lake,
is beyond the Bay watershed so we have even less hope. Lake property owners
have paid over $14 million in fees to DNR since 2000 for lake management but
$3 million plus go to County as Payment in Lieu of Taxes. Anyway, the monies
raised from private property owners is way more than the state has expended.
And now DCL faces huge expense of dredging ( c $15 million), mitigation
projects, shoreline stabilization, etc not included.
Oh, BTW-- this bill is from Senator Edwards and Delegate Beitzel-- a way to
reach across the fracking chasm for a little good will with these folks.
Friends of Deep Creek Lake mission is to promote stewardship, conservation
and restoration of the lake and watershed.

My quick search yielded much less than I imagined. Most are probably already
familiar with the Pimentel et al. studies of costs from the 1999/2000 and
2005 papers. What I didn't know, or at least forgot, was that there was very
little information about tourism impacts in those. In fact the only thing I
can find in those is the following case:
In Florida, exotic aquatic plants, such as hydrilla (Hydrilla verticillata),
water hyacinth (Eichhornia crassipes), and water lettuce (Pistia straiotes),
are altering fish and other aquatic animal species, choking waterways,
altering nutrient cycles, and reducing recreational use of rivers and lakes.
Active control measures of the aquatic weeds have become necessary (OTA
1993). For instance, Florida spends about $14.5 million each year on
hydrilla control (Center et al. 1997). Nevertheless, hydrilla infestations
in just 2 Florida lakes have caused an estimated $10 million in recreational
losses in the lakes annually (Center et al. 1997).
Center at al refers to: Center TD, Frank JH, Dray FA. 1997. Biological
control. Pages 245-266 in Simberloff D, Schmitz DC, Brown TC, eds. Strangers
in Paradise. Washington, DC: Island Press.
I assume there is more out there.

Subject: [MAIPC] Impacts to tourism from invasive species
This may have been a subject recently posted about on the MAIPC listserve
(as it seems slightly familiar to me.), but I was wondering if anyone has
information on ball-park estimates of economic costs specifically to tourism
that can be derived from the harmful impacts posed by invasive species?
