get_morpho: Lake physical morphology

In lawinslow/nlatools: Toolset for the EPA National Lake Assessment Dataset

Description

Combine and return max observed depth and lake area from the NLA lakes

Usage

get_morpho()

Note

For NLA2012, no DEPTHMAX column was supplied. Here it is estimated in the same way as NLA2007, which basically looks at the maximum observed depth in the profile data

Personal Communication with A. Pollard The field crews locate the max depth that they encounter in 30 minutes on the lake. If folks have lake maps or other bathymetry information, this really might be the maximum depth. In other lakes, the crews are simply looking for the deepest area that they encounter in their 30 minute foray around the lake. For this reason, I thought that a column marked as max depth was misleading and it was not included in the NLA 2012 files. It looks like they left the files in roughly the same format as the data sheets
