Answer:

Since you are using a newer version of python3, you would probably have to build opencv from the recipe yourself, which is available at https://github.com/conda-forge/opencv-feedstock

Another option is to have the specific version of python3 in your new environment by creating it like this:
(root) osx:Downloads nwani$ conda list | grep python 
python                    3.6.0                         0 
(root) osx:Downloads nwani$ conda create -yn opencvtest python=3.5.2 
(root) osx:Downloads nwani$ source activate opencvtest 
(opencvtest) osx:Downloads nwani$ conda list | grep python 
python                    3.5.2                         0

The version 3.1.0 builds of opencv are available on the conda-forge channel:
(root) osx:Downloads nwani$ conda search -c conda-forge --spec 'opencv=3*'

opencv                       3.1.0               np110py27_0  conda-forge     
                             3.1.0               np110py34_0  conda-forge     
                             3.1.0               np110py35_0  conda-forge     
                             3.1.0               np111py27_0  conda-forge     
                             3.1.0               np111py34_0  conda-forge     
                             3.1.0               np111py35_0  conda-forge     
                             3.1.0               np110py27_1  conda-forge     
                             3.1.0               np110py34_1  conda-forge     
                             3.1.0               np110py35_1  conda-forge     
                             3.1.0               np111py27_1  conda-forge     
                             3.1.0               np111py34_1  conda-forge     
                             3.1.0               np111py35_1  conda-forge


You can install it like this (Unix Like platform):
(opencvtest) osx:Downloads nwani$ conda install -y -c conda-forge opencv 
(opencvtest) osx:Downloads nwani$ conda list | grep -e python -e opencv
# packages in environment at /Users/nwani/Downloads/m3/envs/opencvtest:
opencv                    3.1.0               np111py35_1    conda-forge
python                    3.5.2                         0  





For Windows platform:

conda insatll -c https://conda.anaconda.org/menpo opencv3

You may also add channel menpo in the Anaconda Navigator and then you can install

the opencv3 via Anaconda Navigator (GUI) easily.

=======================================================

You may like to add the "menpo" channel permanently by:

conda config --add channels menpo
And then opencv can be installed by:

conda install opencv(or opencv3)
