In the walleye bass trends section, edit the bullets and split into two groups. Above the figure have the following bullets (some are new and have been edited so copy exactly):
Recreational fishing in Wisconsin is valued at over $2 billion annually.
Anglers target both walleye and largemouth bass in Wisconsin lakes, but walleye are perceived as preferable and thus important to Wisconsin’s economy and culture.
Then below the bass walleye trend figure, have the following bullets:
There are many possible explanations for the observed changes in Wisconsin lake fish communities, and much interest exists in understanding these trends and whether they can be reversed.
Some believe that largemouth bass are directly responsible for walleye declines. However, evidence to date does not support this claim.
In the "Can you draw..." section, let's have a heading at the very top (above 'can you draw') that states
Water temperature influences the suitability of a lake for walleye and largemouth bass
(formerly the first bullet below the figure, which will now be removed).
In the section under "Can you draw...", most of the first paragraph explains what GDD is. Let's keep the first sentence as is, and make the rest of that paragraph hidden unless the viewer clicks on something to expand. "More information on growing degree days" or "What are growing degree days" as a clickable button? moved to new issue #123
On x-axis label of the 'you draw it' figure, add Lake Temperature to the label above Growing degree days (make the Lake temperature label bigger than the GDD label). moved to issue #124
Reduce bullets below the you draw it figure. They should now read:
In general, walleye reproduce more successfully in cooler lakes, and largemouth bass populations are most abundant in warm lakes.
Both species exhibit a threshold response to temperature, where small changes in temperature can produce big changes in the fish population. Lakes with the best habitat for natural walleye reproduction generally do not have the habitat to support high largemouth bass abundance, and vice versa
These relationships are averages. Other lake characteristics influence the suitability of the lake for each species. For example, walleye can reproduce successfully in large lakes even if they are warm.
In the 'lakes have gotten warmer over 30 years' section, reduce and edit bullets, as follows:
Some lakes have warmed more than others, and some lakes have always been warmer than others - for example, lakes in southern Wisconsin are generally warmer than lakes in northern Wisconsin.
Lake size and depth, water clarity, and surrounding tree cover all influence how lakes respond to climate.
Differences in water temperature affect the suitability of a lake's habitat for supporting different fish species.
In the 'lakes are expected to get warmer in the future' section, split the first bullet into two, as follows:
Scientists agree that the earth will get warmer through the end of the 21st century.
However, the amount of warming depends on actual greenhouse gas emissions and how physical processes such as precipitation and wind speed will change.
change legend labels on future air temperature projections graph to be "High greenhouse gas emissions (A2)" and "Low greenhouse gas emissions (B1)". added to #27
In the 'lakes are expected to get warmer in the future' section in the second set of bullets (below air temperature projections figure and above water temperature projections figure), edit and reduce bullets as follows:
As air temperatures increase, we expect lake temperatures to increase as well. However, not all lakes will respond equally to climate change.
The incredible diversity of lake types in Wisconsin means that we can expect different warming rates in big vs. small lakes, deep vs. shallow lakes, clear vs. turbid lakes.
Understanding differences among lakes in their responses to climate change is a high priority for managing fish populations that are sensitive to warming temperatures.
in future suitability section, split bullets into two sections. Above the Sankey, we should have the following 3 bullets (some of these are new or edited so copy these):
Water temperature is a critical component of fish habitat.
As water temperatures get warmer, many lakes that currently can support natural walleye reproduction are unlikely to continue to have the thermal habitat conditions to do so.
The majority of Wisconsin lakes and total lake area are predicted to have habitat conditions suitable for high largemouth bass densities by the mid-21st century due to warming.
in future suitability section, move the following three bullets after the Sankey but before the map thumbnail. (Some of these are new or edited so copy exactly).
The lakes where walleye are expected to persist are for the most part some of the state's largest and most popular lakes. Therefore, when considered in terms of total lake area, walleye are predicted to persist in a large amount of Wisconsin's total lake area.
Most of the surface area of lakes that support natural walleye reproduction will also support high largemouth bass densities, and largemouth bass are predicted to be supported in a high proportion of the state's total lake area.
The predictions shown here are based only on projected changes in water temperature, and do not account for changes in the fish community, water quality, fish management, or angler behavior that may influence walleye and largemouth bass populations.
After the three are locked in and "I'm done" is chosen, we do a one by one adjustment with text to accompany "you chose 63°F for Lake Trout, that is too warm. Lake Trout prefer X-Y°F"
User can select "reset" to start it again.
If user scrolls past both trigger points (one for making it appear, the other makes them all move) the fish move to the right place.
I assume all this will be fine on mobile w/ drag features, but likely won't work on IE.
Instead of modifying the images themselves, I would rather us be able to use an svg as the background which includes the image within in. Then we can overlay a 100% width/height rect element with a 0-1 opacity value (and some color, like dark grey) so we have more control over these images w/o re-writing them.
this is a subtask in #81 , which I will remove. Build shapefiles with the probabilities and species of dominance as attributes, along with other lake attributes: @gjahansen2 suggests lake name, size, clarity, and max depth
Initial work was done in #28. This issue covers improvements to that figure.
improve tooltips. They are kind of herky-jerky in switching from right to left justified when the words are too long (right side of the fig). Plus, it might make sense to do some line wrapping so the tips aren't too long.
flip the order of some of the "flows" so that the skinnier lines are always on top of the bigger ones (see example below)
make a mobile version that is easier to read the text
right now we do an image swap. We should handle it within a single svg so it is standalone and smoother.
This is pending us actually wanting to move ahead w/ showing acreage, which I will defer to @gjahansen2 on. Won't work on this unless we are going to keep it.
Temperature is key characteristic determining the suitability of a lake for walleye or largemouth bass.
Interactive figure drawing the relationship between DD and each species.
Key points:
Walleye prefer cool water
LMB prefer warm water
The relationship for each species shows a threshold response – the shape is flat above and below a certain point. All lakes below a certain temperature threshold are equally suitable for walleye (on average), and all lakes above that threshold are equally unsuitable for walleye (on average). Reverse is true for LMB.
The relationships between the two species cross – there is a threshold temperature that separates good walleye lakes from good bass lakes.
This is where users discover that bass and walleye prefer different habitats, and that you are more likely to find them in certain lakes.
