Yes it is probably one of the several genera of filamentous algae (FA) that prefers cool water. FA in your pics loos to be in early growth stages. There are cool water and warm water forms. Cool water FA often subsides as water warms up and if nutrients are still abundant warm water FA replaces the cool water forms that are dying back. Example: Some common species of cool water Spirogyra start growth in fall, subsist during winter and thrive as water warms in early spring. Then in June -July Spirogyra dies back and is often is replaced by Cladophora that is known as a 'phosphorus hog'. This cycle in most noticeable in ponds that do not have some form of rooted weed beds nor an abundance of Chara. These ponds rarely have predominant FA problems.
Your pond and all ponds will always have some form or type of FA as a pond inhabitant. Ponds and lakes are never completely rid of some stage of FA growth. FA can exist as small patches of unnoticeable growths.. FA has numerous ways of colonizing ponds. Waterfowl manure contains FA remnants and 'spores'. Plants including FA thrive on utilizing dissolved nutrients. IMO experience FA grows best when the available nutrients are not being used by some other forms of plants be it attached periphyton to submerged rooted higher plants. FA seems to live best when no plants or very few other types of plants are not present to compete with the FA. Some lakes will develop some FA in early Spring that later disappears when the weed beds start their spring/summer growth cycles. Lakes rarely have FA problems because the weed beds in lakes consume most of the dissolved nutrients thus no excess nutrients are present to grow FA. .
